The pressure , volume , number of moles , and Kelvin temperature of an ideal gas are related by the equation pv=nrt, where r is a constant. Prove that the coefficient of volume expansion for an ideal gas is equal to the reciprocal of the Kelvin temperature if the expansion occurs at constant pressure

What definition or equation do you have for the coefficient of volume expansion? That would be a good place to start.

Start with the expression for the coefficient of volume expansion. Since V = nRT/P, what is
[tex]\left(\frac{\partial{V}}{\partial{T}}\right)_{P}\right)[/tex]?
