A quantity of heat 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 `1000 torr`. Final temperature when the pressure manometer indicates an absolute pressure of `400 torr` is

A

`109K`

B

`273K`

C

`373K`

D

`0 K`

Text Solution

Verified by Experts

Melting point of ice `=273 K`
`(P_(1)V_(1))/(T_(1))=(P_(2)V_(2))/(T_(2))`
`(1000)/(273)=(400)/(T_(2))` (at constant `V`)
`T_(2)=109.2`
