One cubic ft of argon gas (molecular weight 39.944) is compressed adiabatically to a pressure of 600 kpa. what will be its new density and temperature? if it is allowed to cool at this new volume back to 10°c what will the corresponding pressure?

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
