Gas because they are less dense
What gets hot and cold faster, solid or gas and why?
The rate at which a substance heats up or cools down depends on its specific heat capacity, which is a measure of how much heat energy is required to raise the temperature of a given amount of the substance by a certain amount. Solid and gas have different molecular structures, leading to differences in their specific heat capacities and thus their ability to heat up or cool down.
In general, gases have lower specific heat capacities compared to solids. This means that gases require less heat energy to raise their temperature compared to solids. Consequently, gases tend to heat up or cool down more quickly than solids.
The molecular structure of a solid is closer and more stable, which makes it difficult for heat energy to penetrate and spread throughout the material. Therefore, solids tend to heat up or cool down more slowly.
On the other hand, gases have molecules that are more loosely packed and can move freely. This allows heat energy to be quickly transferred between gas molecules, resulting in faster heating or cooling.
It is worth noting that specific heat capacity can vary among different types of solids and gases, so the rate of heating or cooling may differ depending on the specific substances involved.
