A given amount of gas A is confined in a chamber of constant volume. When the chamber is immersed in a bath of melting ice, the pressure of the gas is 100 cm Hg.
(a) What is the temperature, when the pressure is 10 cm Hg
(b) What will be the pressure, when the chamber is brought to 100°C?
a) V1 = V2 = V
P1 = 100 cmHg
T1 = 273 K
P2 = 10 cmHg
T2=?
P1V1/T1 = P2V2/T2
100 x V/273 = 10 x V/T2
b) V1 = V2 = V
P1 = 100 cmHg
P2= ?
T1 = 273 K
T2 = 373 K
P1V1/T1 = P2V2/T2
100 x V/273= P2 x V/373
P2 = 136.63 cm of Hg
