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

Options

  1. A5 atm
  2. B6 ~atm
  3. C7 ~atm
  4. D8 atm

Correct answer

B. 6 ~atm

Step-by-step solution
