What happens to the sign of work done on the system when both(V f - V i ) and pressure (p) are negative in the pressure-volume work formula?

Options

  1. AThe work done becomes zero
  2. BThe work done remains negative
  3. CThe work done becomes positive
  4. DThe work done remains unchanged

Correct answer

C. The work done becomes positive

Step-by-step solution

If both(V f - V i )and pressure (p) are negative, the work done on the system becomes positive due to the multiplication of two negative values.
