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
evaporate
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.
The pressure must have been extremely low in the container.
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.
The pressure is 18,87 atmospheres.

The pressure must have been higher than 1 ATM in the container.
The gravitational forces in each direction between the Earth and a sample of matterare equal. The force exerted on the sample by the Earth is what we call the "weight"of the sample. The force exerted by the sample on the Earth is the one that nobodyever mentions, but it's also equal to the weight of the sample. In other words, theweight of the sample on Earth is equal to the weight of the Earth on the sample.
