If the external pressure (P ex ) is greater than the internal pressure (p) of a gas, what sign is assigned to the work done on the system during compression?

Options

  1. APositive
  2. BNegative
  3. CZero
  4. DIt depends on the specific conditions

Correct answer

A. Positive

Step-by-step solution

If the external pressure (P ex ) is greater than the internal pressure (p) during compression, the work done on the system is assigned a positive sign.
