A vessel is filled with an ideal gas at a pressure of `20 atm` and is a temperature of `27^@ C` One - half of the mass is removed from the vessel and the temperature of the remaining gas is increased to `87^@ C`. At this temperature, Find the pressure of the gas.

Text Solution

Verified by Experts

The correct Answer is:
A, B
`p = (n RT)/V or p prop n T`
`:. (p_2)/(p_1)= (n_2 T_2)/(n_1 T_1)`
or `p_2 = ((n_2)/n_1)((T_2)/(T_1))p_1`
= `(1/2)((87 + 273)/(27 + 273)) (20 a t m)`
= `12 a t m`.
