Hint: In thermodynamics , a distinction is made between extensive and intensive properties . The properties whose value does not depend on the quantity of matter present in the system are known as intensive properties. Temperature and pressure belongs to intensive properties. It is a bulk property that does not depend on the size of the matter or that of the system. It is a physical property of that system.
Complete step by step answer:
ENTHALPY :- it depends on the heat of the system that depends on volume of the system and volume depends on mass or size of the system. So it is an extensive property. Thus this option is not correct.
ENTROPY:- it is defined as a randomness degree or disorder degree in the system. More will be given heat more it will show randomness and heat depends on the size of the system. It is an extensive property. So this option is not correct.
DENSITY :- it is usually defined as mass per unit volume. As both mass and volume are extensive properties they cancel out each other and density becomes intensive property. Hence this option is correct.
MASS :- it depends on the size of the system so this is an extensive property. Hence this option is not correct.
Our required answer is C that is density.
An extensive property is a property whose value depends on quantity or size of the matter present in the system. Some of the extensive properties include mass , volume , internal energy , enthalpy , heat capacity are common examples.
