Answer: No, water can't get any wetter
Explanation:
Water is not wet, any fluid can be considered "wet" if wetness is a result of the sensation caused by a movement of fluid over the skin.
The reason Water seems wet-
Because Water is surrounded by other water molecules which is surrounded by itself. The molecules are touching, so water would then seem "wet".
If you're under-water then you are wet, because you're skin has been saturated in a liquid.
In everyday language, we often describe something as being "wet" when it is in contact with or covered by water or another liquid. However, from a scientific standpoint, the term "wet" refers to the ability of a liquid to adhere to a surface.
Cohesion refers to water molecules sticking together, while adhesion refers to water molecules sticking to other substances. These properties allow water to spread and form a thin film over surfaces, making them appear wet.
In this context, water cannot become "more wet" because it already exhibits the characteristic of wetness. When water comes into contact with a surface, it will continue to spread and adhere until it reaches a state of equilibrium. Once the surface is fully covered and no additional water can adhere, the wetness remains constant.
So, while water can interact with and cover surfaces to create a wet sensation, it does not become "more wet" beyond its inherent wetting properties.

Scientists have identified a link in the ice cores between ___________-________ and atmospheric temperatures over thousands of years.
Answer:
Explanation:Ice sheets have one particularly special property. They allow us to go back in time and to sample accumulation, air temperature and air chemistry from another time[1]. Ice core records allow us to generate continuous reconstructions of past climate, going back at least 800,000 years[2]. By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature.
Ice coring has been around since the 1950s. Ice cores have been drilled in ice sheets worldwide, but notably in Greenland[3] and Antarctica[4, 5]. High rates of snow accumulation provide excellent time resolution, and bubbles in the ice core preserve actual samples of the world’s ancient atmosphere[6]. Through analysis of ice cores, scientists learn about glacial-interglacial cycles, changing atmospheric carbon dioxide levels, and climate stability over the last 10,000 years. Many ice cores have been drilled in Antarctica.

USE YOUR OWN WORDS. Each question must have a three sentence long answer!
1. If there is not one scientific method, then what do all scientists have in common?
2. How is a theory similar to and different from a law?
3. What is the difference between data and evidence?
4. Why do scientists use models, and why do all models have limitations?
5. What makes a good scientific question?ANSWER Why do scientific ideas sometimes change?
Answer:
1. Scientists use experimentation and careful observation to collect evidence to support those explanations. Although there is no single scientific method, all types of scientists use the eight science and engineering practices in different orders and combinations to do their work.
2. In simplest terms, a law predicts what happens while a theory proposes why. A theory will never grow up into a law, though the development of one often triggers progress on the other
3.Data is just data and has no intrinsic meaning on its own. Evidence has to be evidence for or of something; an argument, an opinion, a viewpoint or a hypothesis. The evidence you use depends on your argument.
4.All models have limitations because they are not representative of every possible scenario. They use current knowledge and scientific data, but as those are subject to change, the models based off that knowledge and data are subject to change as well. ... Scientific models are not a replacement for experimentation.
5.What makes a good scientific question is that it can be answered by direct observations or with scientific tools. Examples of questions that are not scientific are based on values or opinions like what people believe is right or wrong, or beautiful or ugly. (to the part that says ANSWER ---->) Scientific ideas change over time as our evidence improves. The more experiments we do and the more data we collect, the better our scientific ideas become. ... When a brand-new idea is suggested, the first step is to collect evidence. But even when that evidence is collected, understanding it can be difficult.
How much does the sky weigh?
Answer:
"At eight pounds per gallon, that's another 38,593,169,564 pounds of water in the air. Add it all up, and the total weight of our sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds"
Explanation:
The total weight of our sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds. Sea level atmospheric pressure is 15 pounds per square inch, meaning every square inch of our planet’s surface has 15 pounds of air above it. One square inch is roughly one-third to one-half the size of an adult thumb.
That corresponds to 60,217,344,000 pounds of air for every square mile. Earth has a total surface area of 201,061,929 square miles. Do the math. Our atmosphere weighs 12,107,415,343,900,000,000 pounds.
According to meteorologists, water vapor averages 0.04% of the volume of Earth’s atmosphere. That means the sky holds 4,824,146,196 gallons of water.
At eight pounds per gallon, that’s another 38,593,169,564 pounds of water in the air. Add it all up, and the total weight of our sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds.

Answer: When one object is rubbed against the another, static electricity can be created because the rubbing creates a negative charge, carried by electrons
Explanation:
When we rub a balloon on our head, it causes opposite static charges both on hair and balloon. When the balloon is pulled slowly away from our head, we can see these two opposite static charges attracting one another and making our hair stand up.
On rubbing a balloon on wool, the electrons move from the wool to the balloon's surface. The rubbed part of the balloon has a negative charge. Balloons, the electrical insulators, resist electric charges flowing through them. So only a part of the balloon has negative charge (where the wool is rubbed) and other places remain neutral.
When a balloon is rubbed to wall, it will be attracted to the wall. The charge is not immediately discharged as the wall is an electrical insulator.
When we rub the balloon against metal, the extra electrons in the balloon quickly leave the balloon and move into the metal so the balloon is no longer attracted and does not adhere.

when do the highest tides happen?
(select all that apply.
when the moon is full
When the moon is new
When the moon is in the third quarter
When the moon is in it the first quarter.
When the moon is full, the highest tides happen. Therefore, the first option is correct option.
Tides are the rise and fall of sea levels induced by the moon's and sun's gravitational influences on Earth's oceans. These celestial bodies' gravitational pull causes a tidal bulge on the side of the Earth facing them, as well as a second bulge on the opposite side.
The highest tides, known as spring tides, occur when the moon's and sun's gravitational forces align. This occurs during the full and new moon phases of the moon. During these phases, the sun's and moon's gravitational pulls reinforce each other, resulting in higher high tides and lower low tides.

Write TWO examples of Newton's third law in "The Martian."
For every action force, there is an equal and opposite reaction force.
Answer:
Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down. Another action would be the bomb making the whole in the airlock door which will have a reaction of the ship slowing down
Explanation:
Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down.
What is Newton's Third law?Newton's Third Law is defined as when two bodies come into contact, they exert forces on one another that are both equal in strength and directed in opposing directions.
Ball bouncing: When a ball strikes the ground, it exerts action force on the surface. The ball bounces back as a result of the ground's reaction force. A bird's wings act as an action force, pushing air downward, and act as a reaction force, pushing the bird upward.
Thus, Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down.

is (H2O) water a compound of a element? is Ozone a compound of a element? explain. please help me!!
Answer:
H20 is a compound and ozone is a compound to because the got more then u elements in it
Explanation:
Answer:
Water is a compound because it is composed from two hydrogen atom and one oxygen atom. Water is considered a compound because it is made up of more than one element. By definition, a compound is composed of multiple atoms from different elements. Water has 2 hydrogens and 1 oxygen.
A compound is a combination of more than one element.
A molecule is the smallest particle of an element or a compound.
Oxygen(O) is an element.
O2 - is a molecule which is formed by making a double bond with another Oxygen.
O3 - is a molecule as well, which comprises of three oxygens with two single bonds and one double bond. The resonance structure has a partial positive charge on the central Oxygen and partial negative charges on the end oxygens.
Explanation:
"In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. By this definition, water is both a molecule and a compound. Oxygen gas (O2) and ozone (O3), for example, are substances that are molecules but not compounds."
