The volume of fixed mass of a gas at 47...

The volume of fixed mass of a gas at `47^@C` is `640cm^3` and its pressure is 75 cm of Hg. To which temperature should the gas be related at constant volume to make its pressure double?

Text Solution

Verified by Experts

As volume is a constant,we get, using pressure law
`p_1/T_1=p_2/T_2`
Here `p_1=75cmHg,T_1=273+47=320 K`
and `p_2=2 times 75=150 cmHg`
`75/320 =150 /T_2`
or, `T_2=640K=(640-273)^@C=367^@C`
