We place a 1 mole sample of an ideal monatomic gas in a cylinder with a piston and we heat the gas so it expands and performs work against the piston. Suppose the temperature of the gas increases by 89 celcius while at the same time it performs 700J of work.
a) what is the change of the internal energy of the gas in this process?
b) How much heat does the gas absorb during the process?
