A set of experimental methods that measure the amount of heat received or released by a system when it undergoes a physical or chemical transformation.
The body that receives or yields heat may undergo heating, cooling or change of state. According to these induced changes we have two types of heat: sensible heat and latent heat
Sensitive heat
Sensitive Heat is the amount of heat capable of causing a change in the temperature of a substance without causing a change of state.
Latent heat
While a substance that constitutes an object does not change its state, it is correct to say that its temperature increases when it receives energy, in the form of heat. During the change of state, however, despite receiving or yielding energy, the temperature of the substance remains constant. The amount of heat required to cause a change of state without causing a change in temperature, as long as the pressure remains constant, is called latent heat.
