The isothermal bulk modulus of elasticity of a gas is 1.5 * 100000 N/m^2. What will be its adiabatic bulk modulus of elasticity? Given the ratio of Cp/Cv=1.4

    isothermal bulk modulus of elasticity K(T) = P
    adiabatic bulk modulus of elasticity K(a) = γP,
    where P is the pressure,
    γ = C(p)/ C(v) is ratio of specific heats – adiabatic exponent

    K(a) =γ• K(T) = 1.4•1.5•10^5 =
    =2.1•10^5 N/m^2
