Cloudy nights are often warmer than clear nights. Why is this so?
The clouds generate wind

The clouds trap heat energy during the daylight hours

The clouds store and release heat from the inner Earth

The clouds release heat generated by the friction of air molecules

Answers

Answer 1

Answer: B

Explanation: The clouds act almost like a lid. Think of it like when you put tin foil over food before it goes in the oven. so that even after it is removed from the heat the tin foil traps it causing it to stay warm.

what is condensation transfer of energy?

Answers

Answer:

Condensation happens when molecules in a gas cool down. As the molecules lose heat, they lose energy and slow down. They move closer to other gas molecules. Finally these molecules collect together to form a liquid.

How many moles of water (H2O) are produced when 2 moles of KMnO4 react with plenty of HCl?

2 KMnO4 + 16 HCl → 2 KCl + 2 MnCl2 + 8 H2O + 5 Cl2


A. 2

B. 16

C. 8

D. 5

Answers

Answer:

16

Explanation:

2 KMnO4 (aq) + 16 HCl (aq) → 2 MnCl2 (aq) + 2 KCl (aq) + 5 Cl2 (g) + 8 H2O (l)

This is an oxidation-reduction (redox) reaction:

2 MnVII + 10 e- → 2 MnII (reduction)

10 Cl-I - 10 e- → 10 Cl0 (oxidation)

KMnO4 is an oxidizing agent, HCl is a reducing agent.

This is a gas evolution reaction, Cl2 is the formed gas.

A student uses 0.0821 L• atm/mol • K as the value of the gas constant. What is most likely true about the variables in the ideal gas law?
P has the units of liters • atmospheres, and T has the units of kelvin.
P has the units of liters • atmospheres, and T has the units of degrees Celsius.
V has the units of liters, and T has the units of kelvin.
V has the units of liters, and T has the units of degrees Celsius.

Answers

Answer: V has the units of liters, and T has the units of kelvin.

Ideal gas law: p·V = n·R·T.  

atm · L = mol · L·atm/mol·K · K; both side of equatation have same values.

R = 0,08206 L·atm/mol·K; universal gas constant.  

p is pressure of the gas, unit is standard atmosphere (atm).

V is volume of the gas, unit is liters (L).

n is amount of substance of the gas; unit is mole (mol).

T is temperature of the gas, unit is Kelvin (K

Discuss FOUR ways in which one's acceptance of responsibility can influence
effective communication
4x2​

Answers

Answer:

being responsible is owing up to the possible

consequences of your decision whether it was right or wrong.

communication is a two way process in which there is a messenger and receiver

one of the ways by which a person could be responsible is by saying 'I'

in all the things he would say, instead of 'we'

for example , " We don't like the way you acted a while ago " , change it to i don't like tye way you acted a while ago.

here u r establishing ownership on the things you want to say to the person

Acceptance of Responsibility creates more rapport, increases teamwork, increases honesty, and makes each party look at things from a position of rationality and mutual understanding.

What is Acceptance of Responsibility?

When a person accepts responsibility for their actions and or tasks or their work or their organization, it means that they have elected to become more accountable, looking at things from what they can do to help achieve the collective goal rather than their personal aspirations.

This reduces conflict as most conflicts are borne out of self-interests.

Answers

Fogging a mirror with your breath is a physical change because it involves a phase change of water vapor condensing and adsorbing to the mirror surface. Phase changes are physical changes.

Breaking a bone is a physical change insofar as we're focusing on the  "breaking" part.

Mending a broken bone, however, is a different story. Bones are living things: They consist of tissues that in turn consist of cells. The actual mending process involves some very complicated biochemistry. Suffice it to say that mending a broken bone would be a chemical change.

Burning paper is a chemical change. Burning anything implies combustion, which is a chemical reaction where some fuel is oxidized (usually by oxygen gas, producing carbon dioxide gas and water vapor).

Slicing potatoes for fries is a physical change. You can slice, dice, smash, mash, stretch, bend, compress, or grind a potato: What you will have is still a potato (okay, there are some chemical changes going on as you're rupturing cells in the process, causing them to release their contents which may participate in chemical reactions). But the key, again, is that cutting up some material doesn't fundamentally change the chemical identity of that material.

Mixing sugar with coffee actually involves two physical processes: the mixing and the (presumed) solvation of the solid sugar particles as they dissolve into the coffee. In either case, either mixing or dissolving would be a physical change. The sugar molecules are still in the coffee and are chemically unchanged.

Frying chicken is a chemical change. In fact, frying chicken likely entails several different types of chemical changes. The common thread among them is that frying involves breaking chemical bonds in and on the chicken by the addition of thermal energy, and new chemical bonds end up being formed. That's the hallmark of a chemical change.

A nail rusting is a chemical change. Rusting is an electrochemical process; the familiar corrosion of iron into rust is, at bottom, a chemical reaction where iron reacts with oxygen to form iron oxides (often catalyzed by the presence of water and salts).

A paper ripping is analogous to slicing potatoes: it's a physical change. If you ripped one sheet of paper into two halves, each half would retain all the chemical properties of the original sheet.

Likewise, wood burning is analogous to burning paper, and as such is a chemical change. Again, combustion is a chemical process.

As we said earlier with sugar in coffee, mixing in itself is a physical process. While it may seem like you've permanently changed the nature of the water by dyeing it with food coloring, the molecules comprising the food coloring are simply dispersed within the vast sea of water molecules. There are no intramolecular bonds that are broken or formed; the chemical identities of all the substances here are preserved. So, this is a physical change.

Food molding (rotting) is a chemical change. Rotting is biochemical decomposition: the chemical bonds that make up the food are broken down by enzymes released by the mold.

Writing on paper, whether it be with a pen, pencil, crayon, or marker, is a physical change. The molecules from the writing instrument are physically stuck to the paper. But unless you're writing on paper by, say, burning letters onto it, there are no chemical changes occurring when the writing instrument meets the paper.

As with writing on paper, dyeing fabric can be a physical change. The dye consists of molecules that interact with light in a way that we perceive a certain color. When dyeing fabric, these molecules are transferred and fixed into the fabric by adsorption, absorption, and other intermolecular phenomena. But the molecules of the dye (and the molecules in the fabric) don't experience any breaking and forming of bonds. All of the substances involved retain their chemical identities.

However, it's possible that, depending on the dye, there may be chemical changes involved. Some dyes, appropriate named "reactive dyes," undergo chemical reactions with their substrate (which, in this case, would be the fabric), or dyes may be used that undergo chemical reactions with one another, both of which would constitute chemical changes. And it can depend on what you mean by "dyeing": Bleaching a colored shirt can technically be conceived of as "dyeing" the shirt white, and this process involves cleavage of bonds within the color-producing molecules in the fabric by reacting with the molecules in the bleach.

So, for dyeing fabric, it can be a physical or chemical change depending on the dye.
