Questions & Step-by-Step Solutions
In a thermodynamic cycle, if the net work done by the system is 200 J and the heat absorbed is 300 J, what is the change in internal energy?
Step 1: Understand the First Law of Thermodynamics, which states that the change in internal energy (ΔU) is equal to the heat absorbed (Q) minus the work done by the system (W).
Step 2: Identify the values given in the problem: heat absorbed (Q) is 300 J and net work done (W) is 200 J.
Step 3: Substitute the values into the formula: ΔU = Q - W.
Step 4: Calculate the change in internal energy: ΔU = 300 J - 200 J.
