Question

A closed rigid system experiences a temperature rise of ${50}^{\circ }C$ when a certain process occurs. The heat transferred in the process is 100 kJ. The specific heat at constant plesure for air compressing the system is $1kJ/k{g}^{\circ }C$ and the system contains 3kg of air, What is the work done by the system for this process ?

• A. 0 kJ
• B. 50 kJ
• C. -50 kJ
• D. 150 kJ

Answer 1

The correct option is A 0 kJ

For a closed rigid system of constant volume work done =0
