An ideal gas undergoes a constant pressure process that takes it from State 1 to State 2. The pressure of the gas is 144 kPa. During the process there is 304.0 J of heat transfer to the gas and the thermal energy of the gas increases so that Eth,2 - Eth,1 = 202 J. (a) Find the Work done on the gas during this process. J (b) By how much does the volume change? Please enter your answer as a...
