Question: What is the work done by the system when it expands against a constant external pressure?

Options:

Correct Answer: PΔV

Solution:

The work done by the system during expansion against a constant external pressure is given by W = PΔV.

What is the work done by the system when it expands against a constant external pressure?

What is the work done by the system when it expands against a constant external pressure?

Step 1: Understand that 'work done by the system' refers to the energy used when a system expands.
Step 2: Recognize that this expansion happens against an external pressure, which is constant.
Step 3: Identify the formula for work done during expansion, which is W = PΔV.
Step 4: In the formula, 'W' represents work, 'P' is the constant external pressure, and 'ΔV' is the change in volume (final volume - initial volume).
Step 5: To find the work done, multiply the constant external pressure (P) by the change in volume (ΔV).
