Answer 2

The pressure increases.

Explanation:

• The gases that we deal with in the real world differs from the ideal gases.

• Each of the gases has atleast van der Waals force of attraction between them.

• There may be other interactions like dipole, hydrogen interactions and others.

• But if the attractive forces between the gas molecules suddenly decrease, then the gas will try to escape out more vigorously because there won't be any force drawing them towards each other.

• So it will make the pressure increase.

A gas cylinder contains 320 g oxygen gas at 24.6 atm pressure and 27 degree celsius. What mass of oxygen would escape if first the cylinder were heated to 133 degree celsius and then the value were held open until the gas pressure was 1.00 atm, the temperature being maintained at 133 degree celsius ? (R = 0.0821 L. atm/K/mole).
