Lesson: Heat Capacities of Gasses
In this lesson, we will learn how to relate changes of a gas’s bulk properties to its specific heat capacity and so define the first law of thermodynamics.

When 400 J of heat are slowly added to 10 mol of an ideal monatomic gas, its temperature rises by . What is the work done on the gas?
What is the change in internal energy of the 3.0 mol of dilute monatomic gas after it is heated?
What is the change in internal energy of the 0.50 mol of dilute diatomic gas after it is heated?
What is the change in internal energy of the 15 mol of dilute polyatomic gas after it is heated?
A helium-filled toy balloon has a gauge pressure of 0.200 atm and a volume of 10.0 L. How much greater is the internal energy of the helium in the balloon than it would be at zero gauge pressure?
The specific heat ratio for helium is 1.667.
