The heat specific (c) or thermal mass capacity is a physical quantity that is related to how much heat is received and the thermal variation generated.
The heat specific determines the amount that is needed to increase the temperature by 1°C of 1g of the element. In the international system (SI) specific heat is measured in J/Kg. K (joule per kilogram and per Kelvin).
But it is also common to be measured in cal/g.º C. (calorie per gram and per degree Celsius)
1 cal = 4.186 J

The molar heat capacity or heat specific molar is identified by the relationship between heat capacity and the number of moles present.
When the heat capacity of a substance is for the mole of that substance, it is called molar specific heat.

The thermal capacity or specific heat is determined by the volume or amount of heat present in a body in relation to the variation acting on that body.
Latent heat (L) is the amount of heat received by a body. Here its temperature remains unchanged and its physical state, or form, changes.
In the International System (SI) latent heat is measured in J/Kg (Joule per kilogram) but it can also be measured in cal/g (calorie per gram).
Attention: The latent heat does not depend on the temperature as the specific heat. Because in the change of state, the temperature becomes neutral. An example of this is a melting ice cube. Liquid and solid water have the same temperature.

Sensitive heat is the variation in temperature of a body. When we heat a metal bar, its temperature increases, but its physical state does not change.
