Prove that the isothermal elasticity of an ideal gas is equal to its i

1.	Prove that the isothermal elasticity of an ideal gas is equal to its initial pressure?
Answer» For isothermal process PV = K ................(1) [ T = Constant ]differentiating equation (1) [ K = nRT = Constant ] Pdv + vdp = 0 ⇒ Pdv = − v dp P= −vdpdv P= −B [ B −Bulk modulus ] Hence isothermal elasticity is equal to pressure .
