Question

Which of the following is an extensive property?
A. Heat capacity
B. Density
C. Surface tension
D. Specific heat

Answer 1

Hint: We have to remember that the thermodynamic properties of the system are divided into two categories, they are known as intensive property and an extensive property of the systems. When the size of the system is changed or the system is extended then the property (intensive and extensive) of the system also changes.

Complete step by step answer:
We have to know that the different forms of energy and quantitative relationships amongst them are given by the field of thermodynamics.
We need to remember that the extensive property depends on the total quantity of matter contained in the system. The quantity of matter and the size of the system is changed then these properties are changed. For the purpose of suitability, the total value of property is equal to the sum of the separate parts into the system may be divided. For example: mass, it depends on the quantity of contents present in the system.
We need to know that the intensive property does not depend on the amount of the substance present in the system and it is dependent only upon the nature of the substance present within the system. To describe the state of the system as used as variables at often, the intensive property. For example: pressure, because it does not depend on the quantity of the matter present in the system and it is used as variables to describe the state of a system.
Option B. Density, C. Surface tension and D. Specific heat are intensive properties, because these are independent of the quantity of the matter present in the system and depend only on the nature of the substance.
We have to know that the heat capacity, the amount of heat to be supplied to a given substance to cause a change in temperature.

So, option A. Heat capacity is the correct answer and it is an extensive property.

Note: We also remember that an extensive property may become intensive property by specifying the unit of the amount (substance) concerned. Heat capacity (for the mass of the system) is an extensive property but the specific heat (for the unit mass of the system) is intensive property. Density is intensive property whereas volume and mass are extensive property. The macroscopic particles like pressure, volume, etc. of the system have definite values that are called the state of the system implicate the condition of the system.
