Mathematically, it is the heat capacity of a substance divided by its mass. Specific heat is defined as the amount of heat required to raise one unit of mass of the substance by 1 unit of temperature. Specific heat doesn’t vary with the amount of the substance and is, therefore, a more useful property. A modified form of heat capacity (called specific heat capacity or simply specific heat) is commonly used in physics. Heat capacity is an extensive property, i.e., it depends on the amount and size of the substance.

Specific heat capacity and molar heat capacity are properties derived from the heat capacity of a material. Heat capacity is defined as the amount of heat energy required to raise the temperature of a given mass of a substance by one unit. This is attributed to the handle’s high heat capacity compared to the metal the pan is made from. Also, given the same amount of heat exposure, the rise in the temperature of the plastic handle is much less than that of the metal portion. Of course, it is the handle that protects us, but why doesn’t it get as hot as the pan itself? After all, it is exposed to the same amount of heat.įor starters, a panhandle is typically plastic, which means that it is a poor conductor of heat. Have you ever wondered why we don’t burn ourselves while using a pan? Molar heat capacity is the amount of heat required to raise the temperature of 1 mole of a substance by 1 unit & is calculated by dividing heat capacity by the total number of moles.
