Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which temperature of air do the molecules spread out and take up more space?
A
cold
B
warm
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -When air is heated, the heat energy is absorbed by the individual molecules, causing them to move around more quickly. The molecules move faster and farther apart. When molecules release their energy, they start to slow down and cluster closer together.

Detailed explanation-2: -As the temperature drops, molecules move more slowly, taking up less room. The amount of space the air takes up shrinks, or reduces the air pressure. Why does Hot Air Rise? Warm air rises, and when it rises it becomes cooler.

Detailed explanation-3: -Since the mass of the air remains constant, the density of the air decreases as the temperature increases. In other words, the same mass of warm air occupies a larger volume than the same mass of cold air, so it is less dense.

Detailed explanation-4: -In a gas, the molecules have very weak attractions for one another. Molecules are able to move freely past each other with little interaction between them. The molecules of a gas are much more spread out and move independently compared to the molecules of liquids and solids.
