Question

A gas expands from an initial volume of \( V_1 = 1 \, \text{m}^3 \) to a final volume of \( V_2 = 3 \, \text{m}^3 \) under constant pressure of \( P = 2 \, \text{atm} \). What is the work done by the gas during this expansion?

• A. \( 4 \times 10^5 \, \text{J} \)
• B. \( 6 \times 10^5 \, \text{J} \)
• C. \( 2 \times 10^5 \, \text{J} \)
• D. \( 1 \times 10^5 \, \text{J} \)

Hint:

For constant pressure processes, the work done by a gas is calculated using the formula \( W = P \Delta V \), where \( \Delta V \) is the change in volume and \( P \) is the constant pressure.
