a system A system containing R134a at 16 MPa and 80 degree C

A system containing R-134a at 1.6 MPa and 80 degree C is: Superheated vapor. Saturated vapor. Saturated liquid. Saturated vapor-liquid mixture. Compressed (subcooled) liquid.

Solution

At pressure= 1.6 Mpa

T_sat = 57.88 degree celcius

T= 80 degree celcius > T_sat

Therefore, it is Superheated Vapor.
