Question

If the pressure of a gas is increased by two-fold at a constant volume, the work done by the gas will be _____?

• A. zero
• B. tripled
• C. doubled
• D. quadrupled

Answer 1

Answer:

A. zero

When the pressure of a gas is increased at constant volume, no work is done because the volume does not change. Hence, the work done is zero. The volume is constant, no work is done by the gas (W = 0).
