Question

Why is heat capacity an extensive property?

Answer 1

Thermodynamics may be a branch of science which deals with the study of various kinds of energy and also the quantitative relationship amongst them. It deals with the behaviour of the system in bulk. The properties related to the majority behaviour of matter are called macroscopic properties which are classified into intensive properties and extensive properties.

Complete answer:
Intensive property: The properties which don't depend on the amount of matter present within the system are called intensive property. For example: temperature doesn't depend on the number of matter, so it's an intensive property.

Extensive property: The properties that rely upon the whole matter contained in a very system are defined because of the extensive properties. For example: the quantity of moles depends upon the number of matter present within the solution, so it's an intensive property.

Heat capacity: it's a property of matter which is defined because the amount of warmth to be supplied to a given mass of a substance to supply a unit change in its temperature. The SI unit for warmth capacity is Joule/Kelvin. So, more is that the given mass, greater is going to be the need of the warmth to supply a unit change in its temperature. So, this is often passionate about the amount of matter present within the system.

Thus, it falls within the group of in depth properties. Heat is the internal energy of a substance. This includes kinetic and P.E.. it's impossible to accurately measure all the mechanical energy of the moving particles in an exceedingly substance. The more particles you have got, the more energy you have got, thus heat is an in depth property.

Hence, it's obvious that heat capacity is an intensive property.

Note: Students often get confused between heat capacity and heat capacity. Heat capacity is for the mass of the system hence an in depth property whereas heat capacity is for the unit mass of the system hence an intensive property.
