Anear-surface parcel of moist air is at a pressure of 870 mb (where 100 mb = 1 pa), with a temperature of 12℃ and a relative humidity of 95%. a) what is the saturated vapor pressure (in pa) of the air? explain the physical meaning of saturated vapor pressure. how does it change, if at all, as the temperature increases? how does it change, if at all, as the humidity level (i. e. concentration of water vapor molecules) of air changes?

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
