### Calculating the energy changes when heating an ideal gas

Do we need to memorize the table below? or do we need to understand how to use these numbers and will be given these on quizzes or exams?

If you look on the Laminated Constants and Equations Sheet that we got with the Course Reader you will see on the left side in the middle, Monoatomic ideal gas : U=3/nRT; Cv = 3/2R; Cp = 5/2R. This is what we will be given on a test. We are only given the information on atoms, so it might be useful to know that linear molecules are are just an additional R added to the heat capacities; 5/2R and 7/2R respectively. Given that we have not seen much on linear and nonlinear molecules on our HW, I think it would be safe to just be comfortable with utilizing just the information on atoms for the time being.

Have we seen any examples in the course reader or textbook in which we needed to implement the linear/nonlinear molecule equations?
