Question

Is freezing isobaric?

Answer 1

1. The phase change that occurs during freezing is an isothermal process because it occurs at a constant temperature.
2. The pressure remains constant during an isobaric process, which is a thermodynamic process.
3. This is often accomplished by encouraging the volume to expand or compress which counteracts any pressure increase brought about by heat transfer.
4. Boiling water into steam or freezing water into the ice are two examples of isobaric processes.
5. A gas either expands or contracts to maintain constant pressure, allowing the system or piece of equipment to perform pure work.

Hence, freezing is not isobaric.
