A cylinder contains 0.0100 mol of helium at T = [tex]27.0 ^\circ \text{C}[/tex].
If the presure of the helium is kept constant, how much heat is needed to raise the temperature from 27.0 to 67.0 C?
If the gas is ideal, what is the change in its internal energy?
I got the answer for the first part correct.
My question involves some concepts.
It is because helium is monatomic that the [tex]C_v[/tex] in [tex]\Delta U = nC_{v}\Delta T[/tex] is [tex]\frac{3}{2}R[/tex], correct?
