**1. Homework Statement**

Calculate the volume expansivity, β, for one mole of ideal gas at constant pressure and at room temperature.

**2. Homework Equations**

β=1/V(dV/dT)

**3. The Attempt at a Solution**

Bit stumped on this one, I'm guessing they want it in terms of P as P is not specified.

I used equation of state with n=1 giving PV=RT

> V=RT/P

> β=P/RT(dV/dT)

As the temperature and pressure are constant would dV/dt be zero?

Its from here I am stuck , any help welcome

Thanks
