Question

For an ideal gas pt11 = constant then volume expansion coefficient is equal to-

Answer 1

Answer:

PT = k given AND the coeff. of volume expansion of the gas is given as:

Y =(1/V)(dV/dT)

From ideal gas eqn.,

PV = nRT

or

kV = nRT^2

dV/dT => (2T)*(nR/k)

and

Y = 2nRT/kV

or

2PV/kV => 2P/k => 2P/PT => 2/T
