In a thermodynamic process, the work done by the gas is 200 J and the heat supplied is 300 J. What is the change in internal energy?
Q1. In a thermodynamic process, the work done by the gas is 200 J and the heat supplied is 300 J. What is the change in internal energy?
Answer: 100 J
Explanation: \Delta U = Q - W = 300 - 200 = 100 J. Other options misapply the first law.
