When an air conditioning system cools, it is actually removing heat and transferring it somewhere else. This is evident when you turn on a Spot Cooler and place one hand in front of the cold air nozzle and the other over the warm air exhaust. Sensible heat is the form of heat energy which is most commonly understood because it is sensed by touch or measured directly with a thermometer. When weather reporters say it will be 90 degrees they are usually referring to sensible heat. Latent heat , on the other hand, cannot be sensed by touch or measured with a regular thermometer.
Latent heat causes an object to change state.
This process is reversed when latent heat is added. An object that changes from a solid to a liquid or liquid to vapor is referred to as a change of state. When an object changes state, it transfers heat rapidly. The moisture in the air is called humidity. The ability of air to hold moisture directly relates to its temperature.
