Explanation:

if matter is made of many tiny particles, why does it seem to be continuous? Why doesn’t water seem to behave like sand?

Water and some other molecules exhibit a property know as hydrogen bonding.  A hydrogen atom in one molecule of water is attracted to the oxygen in a neighboring molecules of water.'

The force of this attraction is less than a standard chemical attractive force, but it is real and measurable.

When billions and trillions of water molecules are held together by this force, the small amount of molecule to molecule force is added up to a tremendous force.  That is why even though sulfur is below oxygen on the periodic table, hydrogen sulfide is a gas while hydrogen oxide is a liquid at room temperature.

Hydrogen bonding explains the unique properties of ice, liquid water and steam,We all know water exists in several forms such as solid, liquid and ice. Water boils at 100  C and freezes at 32  F, right? Am I correct? Let us look at some of the chemistry behind forms of water.  

The strong polar bond between water molecules creates water cohesion.

As they are cooled, aggregates of most other substances increase monotonically in density becoming progressively heavier -- the colder they are, the more tightly packed their molecules become. But water possesses a peculiar physical feature: ice expands, so it is lighter than liquid water (i. e., ice floats). When water trapped in rock crevices freezes, it breaks rocks (and pipes).

Water is vital to all known life forms, that is, all those on planet Earth. It is so integral to life as we know it that many biologists cannot even envision life without water (although that might be possible). Indeed, the physical properties of water dictate critical thermal limits for living systems.

In one sci-fi story, an alien refers to humans as "ugly bags of mostly water" -- our bodies are about 60-70% water, depending upon how dehydrated we are at any given time. Humans use massive amounts of freshwater to drink, cook, bathe, flush toilets, do laundry, fill swimming pools, irrigate yards and gardens, run flowing fountains, and for recreation. Precious clean water is often wasted, such as when people leave tap water running while washing their hands or brushing their teeth. The personal water consumption of an average American is about 200 gallons per day, but when industrial and energy usage is added in, per capita freshwater usage is more than 2000 gallons/day. People in third world countries use much less water, of course.

Most freshwater is claimed or "owned" and there is not enough to go around. Approximately half of the world's population of people do not even have adequate access to clean drinking water. One of the major symptoms of the human overpopulation crisis is shortages of available fresh water. Wars will be fought over water.

Hydrogen bonding is a property of water and some other molecules. A hydrogen atom in one water molecule is attracted to an oxygen atom in another water molecule.

Matter is a substance composed of various particle types that occupies physical space and has inertia.

According to modern physics principles, each type of particle has a distinct mass and size. The electron, proton, and neutron are the most well-known examples of material particles.

Atoms and molecules are tiny particles that make up solids, liquids, and gases.

This attraction has a lower force than a standard chemical attractive force, but it is real and measurable.

When this force holds billions and trillions of water molecules together, the small amount of molecule to molecule force adds up to a tremendous force.

Thus, due to these bonds, the water does not seem to behave like sand.

Considering the ideal gas law, the ratio of the final to the initial number of moles in the container is 4.

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P× V = n× R× T

Then ,the number of moles can be expressed as:

[tex]n=\frac{PxV}{RxT}[/tex]

In this case, a container filled with an ideal gas is connected to a reservoir of the same gas so that the number of moles in the container can change. You want to know the ratio of the final to the initial number of moles in the container, this is, [tex]\frac{n_{final} }{n_{initial} }[/tex].

The number of moles [tex]n_{initial}[/tex] can be expressed as:

[tex]n_{initial} =\frac{P_{initial} xV_{initial} }{RxT_{inital} }[/tex]

and the number of moles [tex]n_{final}[/tex] can be expressed as:

[tex]n_{final} =\frac{P_{final} xV_{final} }{RxT_{final} }[/tex]

Then:

[tex]\frac{n_{final} }{n_{initial} } =\frac{\frac{P_{final} xV_{final} }{RxT_{final} }}{\frac{P_{initial} xV_{initial} }{RxT_{initial} }}[/tex]

Being R is a constant number:

[tex]\frac{n_{final} }{n_{initial} } =\frac{P_{final} xV_{final} }{T_{final} }x\frac{T_{initial} }{P_{initial} xV_{initial} }[/tex]

The pressure and volume of the container are each doubled while the temperature is held constant, then you know:

Replacing in the the ratio of the final to the initial number of moles:

[tex]\frac{n_{final} }{n_{initial} } =\frac{2xP_{initial} x2xV_{initial} }{T_{initial} }x\frac{T_{initial} }{P_{initial} xV_{initial} }[/tex]

[tex]\frac{n_{final} }{n_{initial} } =\frac{4xP_{initial} xV_{initial} }{T_{initial} }x\frac{T_{initial} }{P_{initial} xV_{initial} }[/tex]

[tex]\frac{n_{final} }{n_{initial} } =4}[/tex]

Finally, the ratio of the final to the initial number of moles in the container is 4.

The number of particles in 28.5 g of sodium chloride, NaCl is 2.93×10²³ particles

From Avogadro's hypothesis,

1 mole of NaCl = 6.02×10²³ particles

But,

1 mole of NaCl = 23 + 35.5 = 58.5 g

Thus, we can say that:

58.5 g of NaCl = 6.02×10²³ particles

58.5 g of NaCl = 6.02×10²³ particles

Therefore,

28.5 g of NaCl =

[tex] \frac{28.5 \times 6.02 \times {10}^{23} }{58.5} [/tex]

Thus, the number of particles in 28.5 g of sodium chloride, NaCl is 2.93×10²³ particles

Currents are made by wind blowing over the water.

Currents created by wind are formed through the use of warm and cold air. The warm air becomes lighter through expansion, causing it to rise and transform into a warm air current. Cool air is heavier than the warm air, which makes it move to replace the warm air, thus forming a cool air current.

In short, currents are not made by wind blowing over water, but by the characteristics of warm and cool air acting on one another.

Additionally, the rest of the answers can easily be proven true.

Cold currents do cause nearby coastlines to become colder. This is because these winds blow into the coast and affect the temperature. The process also applies to warm air. Warm air can blow into the coastline and warm the area. (With this, both "Cold currents cause nearby coastlines to be colder," and "Warm currents cause nearby coastlines to be warmer," have been shown to be truthful.)

Oceans more more slowly than wind is also correct. The ocean is an uninterrupted surface which winds can peacefully blow across. This lack of disruption causes the winds to move quickly - much faster than even the ocean itself. The ocean('s) currents move slower than the winds. (Therefore, "Oceans move more slowly than wind," had been proven true.)

Oceans hold more heat than atmosphere on land has a simple explanation: the Sun. As we know, this humongous, fiery star we depend on for survival spreads its sunlight all over Earth. The oceans are no exception. The ocean(s) absorb(s) this sunlight and transform(s) it to heat and energy. Since water has a higher capacity for heat compared to air, it can store larger amounts of heat with less of a change in temperature (than air). (For that reason, "Oceans hold more heat than atmosphere on land," is indeed a factual statement.)

All of the options, apart from Currents are made by wind blowing over the water, have been proven true. With that being said, our answer is clear. (Hope this helps - have a lovely week!)
