A vessel is filled with an ideal gas at a pressure of `10` atmospheres and temp `27^(0)C`. Half of the mass of the gas is removed from the vessel the temperature of the remaining gas is increased to `87^(0)C`. Then the pressure of the gas in the vessel will be

Options

A. `5 atm`
B. `18 atm`
C. `7 atm`
D. `8 atm`

Answer

B

Explanation

`P prop mT , (P_(1))/(P_(2)) = (m_(1))/(m_(2)) xx (T_(1))/(T_(2))`
