Question

A polyatomic gas (y = 4/3) is compressed to 1/8th of its
volume adiabatically. If its initial pressure is Po, its new
pressure will be
(a) 8P, (b) 16P, (c) 6P, (d) 2P
nressed adiabatically

Answer 1

Answer:

a 8p qlaaaaaaaaaaaaaa

Answer 2

Answer:

(c) 16P

Explanation:

PV^¥ = constant (adiabatic)

hence P1(V1^¥) = P2(V2^¥)

P2 = P1 [V1/V2]^¥

P2 = P1 [V1/(V1/8]^¥

P2 = P1 × 8^¥

P2 /P1 = 8^(4/3) = 2^4 =16

Hence P2 = 16P1
