Show that the coefficient of volume expansion can be expressed as
β= -1÷ρ (∂ρ÷∂T) keeping P (pressure) constant
Where rho is the density
T is Temperature
β= 1/v (∂v÷∂T) keeping P (pressure ) constant
The Attempt at a Solution
I started with the original equation (β= 1/v (∂v÷∂T) ) ,substituted ρ for 1/v and got stuck . What should I do next? What's the solution?
