1.	Calculate the difference between the two principal specific heat capacities for hydrogen, Given density of hydrogen at a temperature of 270 K and pressure 10 Nm ^(-2) is 0.090 kgm ^(-3).
Answer» Solution :`C _(P) -C_(V)=r, P //rho = r T, r = P //rho T = 10^(5) //0.09 xx 270 = 4115.22 J kg ^(-1) K ^(-1).`
