a piston uses 32 j of energy to do work as 68 j of heat are added to the cylinder of the piston. the change in internal energy of the system is j.
Answer
Explanation:
Step1: Recall the first - law of thermodynamics
The first - law of thermodynamics is given by $\Delta U = Q - W$, where $\Delta U$ is the change in internal energy, $Q$ is the heat added to the system, and $W$ is the work done by the system.
Step2: Identify the values of $Q$ and $W$
We are given that $Q = 68\ J$ (heat added to the system) and $W=32\ J$ (work done by the system).
Step3: Calculate the change in internal energy
Substitute the values into the formula: $\Delta U=Q - W=68 - 32$. $\Delta U = 36\ J$
Answer:
36
