Question
plz answer those questions!!! Thanks!!
Refrigerant 134a is saturated vapor at 5 bar and 15.74 degree C. In what state will it be, if the temperature is doubled at 5 bar? Critical point Compressed liquid Saturated liquid Liquid-vapor mixture Superheated vapor Propane, initially at its critical point, goes through an isothermal expansion process. The final state of the propane is Saturated vapor Saturated liquid Compressed liquid Superheated vapor Liquid-vapor mixture Refrigerant 134a contained in a rigid tank is initially at its critical point. If it is cooled in the tank to a final state, what would that state be? Saturated liquid Superheated vapor Liquid-vapor mixture Saturated vapor Compressed liquid A substance is at a pressure that is a thousand times below its critical pressure. The substance would be considered as A superheated vapor An ideal gas A saturated liquid A saturated vapor A liquid-vapor mixture When the temperature of an ideal gas is doubled while its volume is halved, what would happen to the pressure? Pressure would be quadrupled Pressure would he quartered Pressure would be doubled Pressure would be halved Pressure would be tripled
