Question

During adiabatic process pressure (P) versus density (r) equation is –

• A. Pr^g = constant
• B. Pr^–g = constant
• C. P^gr^1+g = constant
• D. P^1/gr^g = constant

Answer 1

Answer: (B)

Pr^–g = constant

Answer 2

In adiabatic process

PV^g = constant … (1)

density r = $\frac { \mathrm { m } } { \mathrm { V } }$

or r µ V^–1

\ Eq. (1) can be written as

Pr^–g = constant
