Last updated: 7/8/2022

A mole of helium in the process of expansion has constant molar heat capacity during the process which is equal to C = 15 J/ (mol - K). The gas does 20 J work during the process. Take R = 25/3 J/mol K The heat given to the gas is 120 J The temperature of the gas increases by 8 K Heat extracted from the gas is 80 J The pressure of the gas increases during the process.
