Question

Definite quantity of an ideal gas is confined in a container of constant volume. when the container is immersed in a bath of melting ice . the pressure of the gas is 800mm of hg. find the temprature when the gas pressure is 400 mm of hg?

Answer 1

P1V1/T1 = P2V2/T2
Volume is constant hence
P1/T1 = P2/T2
800/T1 = 400/T2
T2 = T1/2

Answer 2

Answer:

The quantity of an ideal gas is confined in a container of constant volume. when the container is immersed in a bath of melting ice . the pressure of the gas is 800mm of hg. when the gas pressure is 400 mm of hg the temperature would be

Explanation:

Given:

• $V_{1}=V_{2}=V$
• $P_{1}=800mm Hg$
• $P_{2}=400mm Hg$
• $T_{1} =273K$

• $T_{2}=?K$

Formula:

• $P_{1} V_{1}/T_{1}$=$P_{2}V_{2}/T_{2}$

Solution:

• 800*V/273=400*V/$T_{2}$
• $T_{2}=$136.5mm Hg
