Three moles of an ideal monatomic gas expands at a constant pressure of 2.60 atm; the volume of the gas changes from 3.30 multiply.gif 10-2 m3 to4.00 multiply.gif 10-2 m3.
(a) Calculate the initial and final temperatures of the gas.
(b) Calculate the amount of work the gas does in expanding.
(c) Calculate the amount of heat added to the gas.
(d) Calculate the change in internal energy of the gas.
