Thermodynamic work is the work done by or on a system during a thermodynamic process. It is a form of energy transfer that occurs due to a change in the state of a system. The formula for thermodynamic work is given by:
W = -PΔV
where W is the work done, P is the pressure, and ΔV is the change in volume.
Explanation:
Intensive and extensive properties are the two types of properties that are used to describe a thermodynamic system. Intensive properties do not depend on the size of the system, whereas extensive properties depend on the size of the system.
Option A: Two intensive properties
If we take two intensive properties, their product will not give us the thermodynamic work because intensive properties do not depend on the size of the system. Therefore, option A is incorrect.
Option B: Two extensive properties
If we take two extensive properties, their product will not give us the thermodynamic work because extensive properties depend on the size of the system. Therefore, option B is incorrect.
Option C: An intensive property and change in an extensive property
If we take an intensive property, such as pressure, and a change in an extensive property, such as volume, their product will give us the thermodynamic work. This is because work is a form of energy transfer that occurs due to a change in the state of the system. Therefore, option C is correct.
Option D: An extensive property and change in an intensive property
If we take an extensive property, such as volume, and a change in an intensive property, such as temperature, their product will not give us the thermodynamic work because work is a function of pressure and volume, not temperature. Therefore, option D is incorrect.
Conclusion:
Thermodynamic work is the product of an intensive property, such as pressure, and a change in an extensive property, such as volume. This is because work is a form of energy transfer that occurs due to a change in the state of the system.

Work is given by either pdv. Here pressure is intensive and volume is extensive property. Pump or compressor work is Thermodynamic.
