Answer:

A. London dispersion

Explanation:

London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.

How does liquid turn into gas? (Question for my sister)
kodGreya [7K]
If you were to take water (like many other materials) and break it up into almost the smallest things you could, you’d get molecules. If the molecules are stuck together really tightly in a regular pattern, then they’re called a solid. The solid form of water is ice. This actually makes a lot of sense, because it certainly does seem like all the little parts of a solid (like ice) are stuck together very tightly.

When you heat something up, it makes the molecules move faster. If you heat up a typical solid, it melts and becomes a liquid. In a liquid (like water), the molecules are still stuck together, but they can move around some. What actually happens is that the molecules are still sort of sticking together, but they’re constantly breaking apart and sticking to different molecules. This also makes sense when you think about water. Water sort of sticks together, but it breaks apart /really/ easily.

If you heat a liquid like water up even more (like if you put it in a pot on the stove), then the molecules will move around so fast that they can’t even hold on to each other at all. When this happens, all of the molecules go flying apart and become a gas (like when you boil water to make steam). The process of gas molecules leaving the liquid to go into the gas is called "evaporation." The opposite process is called "condensation."

The pictures below show samples of different substances.
Mrrafil [7]

Answer:

C. Yes, if each sample contains 6.02 x 10²³ atoms.

Explanation:

It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.

6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.

  • If the amount of matter in the given substance is at least one mole, it is possible that they are made up of one mole each of each substance.
  • If they contain lesser amount of atoms, then it is not up to one mole of substance.
  • But if it is greater, then, we can have even more than one mole of substance.

A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.

Answer:

49.5J/°C

Explanation:

The hot water lost some energy that is gained for cold water and the calorimeter.

The equation is:

Q(Hot water) = Q(Cold water) + Q(Calorimeter)

<em>Where:</em>

Q(Hot water) = S*m*ΔT = 4.184J/g°C*54.56g*(80.4°C-59.4°C) = 4794J

Q(Cold water) = S*m*ΔT = 4.184J/g°C*47.24g*(59.4°C-40°C) = 3834J

That means the heat gained by the calorimeter is

Q(Calorimeter) = 4794J - 3834J = 960J

The calorimeter constant is the heat gained per °C. The change in temperature of the calorimeter is:

59.4°C-40°C = 19.4°C

And calorimeter constant is:

960J/19.4°C =

<h3>49.5J/°C</h3>
