Question
A given quantity of an ideal gas is at pressure p and absolute temperature T. The isothermal bulk modulus of the gas is
Options
A.
B.p
C.
D.2p
Solution
In isothermal process
pV = constant
∴ pdV + Vdp = 0
or
∴ Bulk modulus, B = -
V
∴
∴ B = p
Note : Adiabatic bulk modulus is given by B = γp.
pV = constant
∴ pdV + Vdp = 0
or
∴ Bulk modulus, B = -
V ∴
∴ B = p
Note : Adiabatic bulk modulus is given by B = γp.
