Short Answer

We ordinarily say that ΔU = 0 for an isothermal process. Does this assume no phase change takes place? Explain your answer.

During the transformation of the phase, the temperature remains the same but the state of the system changes. So, the phase change can take place.

Step 1: Explanation:

· All phase changes are isothermal in nature.

· Let us consider an example like the melting of ice. Melting of ice is an isothermal process.

· During the melting process, the phase change occurs that is the ice melts into liquid with the temperature being constant.
