Acertain amount of ideal monatomic gas is maintained at constant volume as it is cooled from 455 k to 405 k. this feat is accomplished by removing 400j of energy (as heat flow) from the gas. how much work is done by the gas during this process?

If the spring constant k of a pogo stick is 3500 n m and the weight of the person on the pogo stick is 700 n, how much is the spring in the botom of the pogo stick compressed?

Apersons beliefs and general outlook, which act like filters on the information they receive are called ?

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator.
