For ideal gases, why is Cp 5/2R and Cv 3/2R

You can find those values according to the equipartition theorem for an ideal gas and use U=3/2nRT to substitute and find the values for Cp and Cv. It's on the constant and equations sheet. Just remember to use those for monoatomic ideal gases.

I think it has something to do with the fact that Cp= Cv+R. Since Cv=3/2 R that would mean Cp= 3/2R + R = 5/2R

What does R refer to?

R is the gas constant

R is the gas constant and it is usually in the units of J/K/mol.
