Adiabatic modulus of elasticity of a gas is $2.1 \times 10^{5} N m^{- 2} .$ What will be its isothermal modulus of elasticity? $(\frac{C_{p}}{C_{v}} = 1.4)$

Options:

Answer:

Solution:

$\frac{E_{s}}{E_{T}} = γ = \frac{C_{P}}{C_{V}} = 1.4$

$\frac{2.1 \times 10^{5}}{E_{T}} = 1.4$

$o r E_{T} = \frac{2.1 \times 10^{5}}{1.4}$

$= 1.5 \times 10^{5} N m^{- 2}$
