Question

Water initially saturated vapor at 4.5 bar, fills a closed, rigid container. The water is heated until its temperature is 360.

A. The water undergoes isothermal compression

B. The water undergoes isobaric expansion

C. The water undergoes adiabatic cooling

D. The water undergoes isochoric process

Answer 1

The correct option is D: The water undergoes an isochoric process, as the volume is constant while the temperature of the saturated vapor increases when heated in a closed, rigid container.

This correct answer is D.

Step-by-step explanation:

The student's question is about a thermodynamic process taking place in a closed, rigid container with saturated water vapor.

When the water is heated in such a container, since the volume cannot change, the only thermodynamic process that can occur is an isochoric process, which is a process at constant volume.

In this case, the water cannot undergo isothermal compression (since the temperature is rising, not constant), isobaric expansion (since the pressure likely changes if heated at constant volume), or adiabatic cooling (since heat is being added, not isolated).

This correct answer is D.
