When gas is cooled it?

It contracts and takes up less space or has less preasure. If it is cooled enough it can condense (turn into a liquid) or sublimate (turn into a solid).


What happens when gas cool down?

When cooled enough it will condense into a liquid. The required temperature changes with the substance.


What happens to the atoms of a gas when the gas is cooled?

The atoms loose kenetic energy and bounce around slower. This causes the gas to have less preasure and, if cooled enough, can cause the gas to condense into a liquid or sublimate into a solid.


Why does a gass expand when heated and contract when cooled?

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.

What can go from a gas to a liquid?

A gas condenses into liquid phase if its cooled below its critical temperatureand pressurized. If pressure is above the gas triple point pressure, coolingis enough to condense the gas to liquid phase.A gas below its critical temperature is called a vapour.


Scientists think that a few hundred million years or so after the Big Ban space cooled off enough for matter to form This matter spread out around the universe with no structure but each little bit?

When did earth cool enough for the water in its atmosphere to condense and cause rain?

This may happen is a gas cools enough?

The gas may condense via condensation


When cooled enough water vapor into water droplets?

condenses


If a ice is left on a table and turns into water will it evaporate?

no because there is not enough heat it possibly could but it wouldn't be able to condense (not cold enough)


When cooled enough water vapor into tiny water droplet?

yes when water vapor is cooled its molecules lose energy and come closer together therefore changing state into liquid. on a microscale this is what happens in the atmosphere to create fog. to have clouds we need something called a condensation nuclei which a small surface of which the water can condense on. because these are very small they are easily manipulated by air currents so a simple updraft is enough to suspend a giant cloud in the air because it has a very large surface area.
