What happens to the volume of the container if the temperature of the gas decreases, The pressure of the gas and the number of moles stays the same. Srry, my teacher didn’t explain any of this stuff, and I can’t find any sites that answer this specifically.help is greatly appreciated^_^

Answer #1

If the container is rigid, it’s volume does not change under pressure, or in a vacuum Decreasing the temperature of a gas in a sealed container, decreases it’s pressure, and at low enough temperature it becomes (in most cases) a liquid, and then a solid. Example: dry ice, which is frozen CO2 upon warming the molecules vibrate again, and move further apart, thus an increase in pressure - which is why you should not put dry ice into a sealed container and warm it…it will cause the container to explode. At atmospheric pressure dry ice goes from solid state to gaseous state without a liquid state. under pressure CO2, like Nitrogen, has a liquid state, although Nitrogen will maintain it’s liquid state at low temperature, at one atmosphere…which is why it can be kept in a Dewer flask, such as doctors use to freeze off warts.

Answer #2

I thought nothing would happen but if there’s a whole question about it I’m sure that’s not the answer. Good luck though!

Answer #3

I know, it makes know sense, how can those things affect the volume of the container.

Answer #4

wow, my science teacher would be really disappointed in me right about now… :p
