Which of the following is the property of a system?

Explanation:

Properties

All measurable characteristics of a system are known as properties.

Eg. Pressure, volume, temperature, internal energy, density etc.

There are two types of properties:

Extensive property

• Those properties which depend on mass are known as extensive properties.
• Examples are volume, energy, enthalpy, etc.

Intensive property

• Those properties which don't depend on mass are known as intensive properties.
• Examples are pressure, temperature, density, viscosity.

Important Points

• The ratio of two extensive properties is an intensive property.
• Specific properties are intensive properties. For example specific volume, specific energy etc.
• If a property divides with space then it is extensive property otherwise the property will be intensive.
• Property is a point function.
• Property is independent of past history.
• In a cycle change in property is equal to zero.
• Properties are exact differential.

Note: Heat, work, and entropy generation are path functions, they are not properties.
