Properties of Matter 1 Question 13

13. A given quantity of an ideal gas is at pressure p and absolute temperature T. The isothermal bulk modulus of the gas is

(a) 23p

(b) p

(c) 32p

(d) 2p

Show Answer

Answer:

Correct Answer: 13. 12(YAL)x2

Solution:

  1. In isothermal process

pV= constant pdV+Vdp=0 or (dpdV)=(pV) Bulk modulus, B=(dpdV/V)=(dpdV)VB=[(pV)V]=pB=p

NOTE Adiabatic bulk modulus is given by B=γP.
