Options:

Correct Answer: PΔV

Exam Year: 2019

Solution:

The work done by an ideal gas during an isobaric (constant pressure) expansion is given by W = PΔV.

What is the work done by an ideal gas during an isobaric expansion? (2019)

Step 1: Understand that isobaric means the pressure (P) remains constant during the process.
Step 2: Identify that during an expansion, the volume of the gas changes from an initial volume (V1) to a final volume (V2).
Step 3: Calculate the change in volume (ΔV) using the formula ΔV = V2 - V1.
Step 4: Use the formula for work done (W) during isobaric expansion, which is W = P * ΔV.
Step 5: Substitute the constant pressure (P) and the change in volume (ΔV) into the formula to find the work done.
