What happens when gas is heated and cooled in a container?

Answer 1

When steaming something covered with a lid, over the stove, and you lift the lid, there is condensation....the gas turns back into a liquid. Same would happen in the above named situation. It would turn back into it's original state...liquid.

Answer 2

When a liquid is heated the molecules gain more kinetic energy and move faster. If they gain enough energy they can break the van der waal bonds (intermolecular bonds) between the molecules and become gas particles (evaporation). When a liquid is cooled the molecules loose kinetic energy and move slower. If a liquid is cooled enough stronger bonds are formed between the molecules and a solid is form (solidification)
The number of liquid molecules vaporizing equals

the number of vapor molecules condensing

Answer 3

When gas is heated in a container, its particles gain energy and move faster, causing an increase in pressure. When gas is cooled in a container, its particles lose energy and move slower, leading to a decrease in pressure. Heating and cooling can also affect the volume of the gas, following the ideal gas law.

Answer 4

The gas molecules receive energy and start to vibrate. The pressure within the container increases. The container could explode.

Answer 5

The pressure is reduced inside the container (see collapsing can experiment) - if cool enough the gas will condensate or even freeze.

Answer 6

The steam builds up pressure and once it reaches a certain point, the lid blows off.

Answer 7

Heating lead to an increase of pressure.
Cooling lead to a decrease of pressure.
