Question

Isothermal elasticity for a gas (having gamma=5/3)

is
3 * 10^5 N/m2. If the same gas is undergoing
adiabatic change then adiabatic elasticity at that
instant is
(1) 3 x 105 N/m2
(2) 5 x 105 N/m2
(3) 6 x 105 N/m2
(4) 10 x 105 N/m2​

Answer 1

2nd option is correct

Isothermal mod.elasticity=p\v =3*105n\m2

adiabatic mod.elasticity =vp\v

=5\3*3*105

5*105n\m2

i hope this helpful for u if rate it
