Question

A container of gas at 2.7 atm pressure and 133 ∘C is compressed at constant temperature until the volume is halved. It is then further compressed at constant pressure until the volume is halved again.
a) What is the final pressure (atm)?
b) What is the final temperature (C)?

Answer 1

Answer:

5.4atm ,66.5°c

Explanation:

Note that we are given the initial temperature to constant,

Thus PV = constant

so volume halved means pressure doubled from P1v1= p2v2

Hence P2 = 2.7*2atm = 5.4atm

next step we keep pressure constant thenV/T = constant

so volume halved means temperature also halved from V1/T1= v2/T2

Hence

T = 133/2 = 66.5°C
