They slow down and come closer together forming a liquid. Then further cooling will produce a solid.
The gas particles will spread out to encompass the entire volume of the container. The particles are constantly in motion and will run into the walls of the container creating pressure (basically). If heated, the particles will move faster, and slower if cooled.
this is known as liquifaction if the gas is cooled to liquid.
When a gas is heated up, the particles within the gas start to move faster, going farther apart (expansion). When a gas is cooled, the particles slow down and it starts to condense (contract), and if cooled enough, into a liquid.
ereee
Condensation happens when a gas is cooled. As the gas cools, the particles loose energy,move more slowly and have a greater attraction for one another.
Gas pressure decreases when cooling down a closed container.
When anything is cooled its particles move more slowly.
it loses energy that makes it not move as quickly, therefore it gets smaller. that answer your question?
When particles in a liquid are cooled, they lose energy and move more slowly. Eventually, the particles will slow down enough to form a solid as the attractive forces between them overcome their kinetic energy.
they tend to vibrate
The viscosity increase when the temperature decrease.
When materials are heated, the particles gain kinetic energy and move faster, leading to expansion of the material. Conversely, when materials are cooled, the particles lose kinetic energy and move slower, causing the material to contract or condense.
