FAQs on Pressure-Volume Work: Irreversible Video Lecture - Chemistry for JEE Main & Advanced

1. What is pressure-volume work?

Ans. Pressure-volume work is a type of work done by a system when there is a change in volume against an external pressure. It is the work done to move the system's boundaries and change its volume.

2. How is pressure-volume work calculated?

Ans. The pressure-volume work can be calculated using the formula: Work = -PΔV, where P is the external pressure and ΔV is the change in volume. The negative sign indicates that the work is done on the system.

3. What is the difference between reversible and irreversible pressure-volume work?

Ans. Reversible pressure-volume work refers to a process that can be reversed, meaning that the system can return to its original state without any losses or changes in its surroundings. On the other hand, irreversible pressure-volume work refers to a process that cannot be reversed, resulting in losses and changes in the system and its surroundings.

4. What are some examples of irreversible pressure-volume work?

Ans. Some examples of irreversible pressure-volume work include the expansion of a gas against a constant external pressure, the compression of a gas with friction, or the expansion of a gas through a valve that is not perfectly insulated.

5. How does irreversible pressure-volume work impact the efficiency of a system?

Ans. Irreversible pressure-volume work usually leads to a decrease in the efficiency of a system. This is because irreversible processes result in energy losses through factors such as friction, heat transfer, or other forms of dissipation. These energy losses reduce the overall efficiency of the system.
