प्रश्न
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 cmHg.
- What is the temperature when the pressure is 10cmHg?
- What will be the pressure when the chamber is brought to 100°C
उत्तर
(a) V1 = V2 = V
P1 = 100 cm Hg
T1 = 273 K
P2 = 10 cm Hg
T2= ?
`("P"_1 "V"_1)/"T"_1 = ("P"_2 "V"_2)/"T"_2`
`(100 xx"V")/273 = (10 xx"V")/"T"_2`
`"T"_2 = 27.3 "K"`
(b) V1 = V2 = V
P1 = 100 cmHg
P2= ?
T1 = 273 K
T2 = 373 K
`("P"_1 "V"_1)/"T"_1 = ("P"_2 "V"_2)/"T"_2`
`(100 xx"V")/273 = ("P"_2 xx"V")/373`
`"P"_2 = 136.63 "cm of Hg"`
