    Graduate Demonstrate that Cv depends only on temperature

    Well I haven't. I wouldn't bother posting and waiting for an answer if I had found something convincing... As I understand it, Internal Energy is defined as (for monatomic gases) the mean Kinetic Energy of all molecules and Temperature is a measurement of it : Nm<v2>/2 = U = 3NkBT/2...

    Graduate Demonstrate that Cv depends only on temperature

    Ok, but do you have any idea of how I could prove that it depends only on temperature ? (other than experimentally) I can't seem to find anything about this on the internet or my textbook.

    Graduate Demonstrate that Cv depends only on temperature

    Hello, I stumbled upon this question and I don't know how to answer it... I know that Cv is defined as Cv = δQv/dT = (∂U/∂T)v but I thought it's value was determined by the nature of the gas only (3/2 for monoatomic and 5/2 for diatomic). Can someone help me figure this out ?
