When pressure is not constant during compression and changes in a series of finite steps, how is the total work done on the gas calculated?

Options

  1. ABy multiplying the final pressure by the change in volume
  2. BBy taking the integral of pressure with respect to volume
  3. CBy summing the work done at each step over all the steps
  4. DBy using the ideal gas law

Correct answer

C. By summing the work done at each step over all the steps

Step-by-step solution

When pressure changes in a series of finite steps during compression, the total work done on the gas is calculated by summing the work done at each step over all the steps.
