Answer: The heat that an object absorbs or releases when its temperature rises or falls without changing its original phase during heating or cooling is called sensible heat. It can make people feel obvious changes in temperature and can usually be measured with a thermometer. For example, the heat absorbed by water when the temperature rises from 20
to 80 is called sensible heat.
In the process of an object absorbing or releasing heat, its phase changes (such as gas turning into liquid...), but the temperature does not change. This absorbed or released heat is called latent heat. Latent heat cannot be measured with a thermometer and cannot be felt by the human body, but it can be calculated through experiments.
After saturated air releases heat, part of the water vapor will turn into liquid water, and the temperature of the saturated air does not drop at this time. This part of the released heat is latent heat.
