What is the difference between specific heat and heat capacity

Heat capacity gives the amount of energy required to raise the temperature of a given sample of a substance by 1 o C. Specific heat gives the heat capacity per kilogram of a substance.

Heat capacity is directly proportional to the mass of an object. Specific heat does not depend on the mass of an object, as it is defined per unit mass. Heat capacity has SI units J K Specific heat has SI units J kg -1 K About the Author: Nipun.

This happens because every material has its heat capacity. And this is known as specific heat capacity or specific heat. Specific heat or specific heat capacity can be seen in day to day life, it is chemical reasoning of heat process in different materials, which can be calculated theoretically through its formula. Unlike specific heat, heat capacity is dependent on the mass of the substance. Heat capacity depends on the mass of the substance. Unlike specific heat, it does not include the mass of substance due to which unit does not include kilograms or grams.

Heat capacity can be explained through an example like iron heats or cools down quickly because it has low heat capacity. On the other hand, water takes time to get hot or cold because it has a high heat capacity. In central heating systems such as hot water is used to carry thermal energy through pipes from the boiler to radiators. These radiators are fixed inside the house at suitable places.

Equation 3 show that the heat capacity of a body is equal to the product of its mass of the body and its specific heat capacity. That is; 5 kg of water needs Joules of heat for every 1 K rise in its temperature. Thus, the larger is the quantity of a substance, the large will be its heat capacity.

Matter can be changed from one state to another. For such a change to occur, thermal energy is added to or removed from a substance. For related Topics visit our page: Modern Physics.
