Question

A substance is under conditions of pressure and temperature below the critical point, has 50 ° C with a Psat = 1.952 kPa, and has a quality of 0.5. If a process is supplied with energy while maintaining constant temperature and pressure, select the option that is false:

The process will end at the critical point

At the beginning the volume of the saturated liquid is equal to the volume of saturated steam

All other options are false

The system can not receive energy if the temperature is constant

The quality will remain at 0.5

Explanation / Answer

(a) False. The process will not end at critical point Because Temperature remains constant so temperature will not increase.

(b) False. Volume of saturated liquid is much much smaller than saturated vapor

(c) No 1 option is correct

(d) False. The system can recieve energy when Temperature is constant Like in case of phase transformation

when we convert liquid to vapor, the energy is supplied. liquid taking the latent heat and converted to vapor but Temperature and pressure remain constant.

(e) True quality remain same as temperature is not changed.
