There is not going to be pressure build up in the system, that is isobaric process.

Explanation:

Assumptions to be made

1. No mass is gained or lost during the heating process.

2. There are no friction losses, so work is transmitted efficiently.

3. It was started the water in the drum and its surrounding have same temperature.

4. This system is closed, so there is no mass transfer across its boundaries.
