A monoatomic gas supplied the heat Q very slowly keeping the pressure constant. The work done by the gas will be

Options

  1. A2 3 Q
  2. B3 5 Q
  3. C2 5 Q
  4. D1 5 Q

Correct answer

A. 2 3 Q

Step-by-step solution

For monoatomic gas at constant pressure U Q = 1 3 or U= Q 3 Now applying first law of thermodynamics aligned W & = Q- U & =Q- Q 3 = 2 Q 3 aligned
