일반물리학 1 — The Kinetic Theory of Gases: Problem 4

4 When 22.5 J was added as heat to a particular ideal gas, the volume of the gas changed from 50.0 cm3 to 100 cm3 while the pressure remained at 1.00 atm. (a) By how much did the internal energy of the gas change? If the quantity of gas present was 2.00 × 10−3 mol, find (b) Cp and (c) CV.
