Question:
At 25 °C and 1 atmospheric pressure (Note that 1 atm=101.3 kPa), an ideal monatomic gas takes up a volume of 100 L. The gas undergoes adiabatic expansion. The work done by the gas is 7000 J.
(a) Calculate the number of mole of the ideal monatomic gas.
(b) Sketch a P-V graph indicating the adiabatic expansion of the gas. Also indicate on the graph
two isothermal lines, one for the initial temperature and one for the final temperature.
(c) Calculate the internal energy change of the gas.
(d) Calculate the final temperature of this ideal monatomic gas this expansion.
