Question

A gas undergoes a process in which its
pressure P and volume V are related as
VP constconstant. The bulk modulus
of the gas in this process is:​

Answer 1

Answer:

B = P

Explanation:

Dear Friend,

Since PV = constant,

d(PV) = 0 (as derivative of a constant is 0)

Therefore PdV + Vdp = 0

1. PdV = -Vdp --------------  (1)  

• Bulk Modulus = - dP x V/dV -----------  (2) { IMPORTANT}

From equation 1 --------> dp = -PdV/V

Substituting in 2

B = P

Hope it helps!

EXTRA INFO:

• If  a question were to arise, questioning whether heat flow was constant or temperature was constant : The answer would be temperature
• This type of process, where PV = constant , is termed as an isothermal process
