In a gas intermolecular forces are weakened and the expansion is easily possible.

The pressure must have been extremely low in the container.

The pressure must have been higher than 1 ATM in the container.
The pressure of a sample of helium in a 1.00- L container is 0.988 atm. What is the new pressure if the sample is placed in a 200- L container
It rises, because you have packed more atoms into the same space.
Even if the pressure inside a container is equal to the pressure outside a container, there is still pressure. It's like pushing a friend one way while he pushes you back. Neither of you may be moving, but you're still pushing. The sample of gas would exert exactly one atmosphere of pressure (or 100 kPa) on the container. The question then becomes whether the container can withstand that pressure.
Yes. Any sample of gas in a closed container will exert pressure on the container, as long as the temperature of the gas is above absolute zero. You can force the gas into a smaller volume by shrinking the container, but that action raises the temperature and pressure of the gas.
