What happens to the particles in a gas when the temperature increases?
The atoms or molecules of a gas will increase in kinetic energy when that gas is heated. Those atoms or molecules will exhibit an increase in their vibrational energy, and they will expand and move farther apart if they are not confined.
What particles are in a constant state of motion and raely stick together would it be a gas or solid or plasma or liquid?
Liquids and gases (and plasma, a form of heated gas) have molecules which are not fixed, but move about. The molecules in solids may also move, but more often "oscillate" around a given position.
As the amount of water vapor in the air increases?
In a liquid, the molecules are moving about. During evaporation, some molecules near the surface have enough kinetic energy to escape the bonds within the liquid. When the liquid is heated more energy is supplied to the molecules giving them increased energy and more are able to escape the bonding in the liquid
What are the 2 reasons why a decrease in temperature slows a chemical reaction?
Decreasing the temperature reduces the kinetic energy of the molecules involved. This means that fewer molecules have the activation energy required to actually react. It also means that molecules will collide less often.
When liquid water is heated by the Sun it often evaporates becoming a gas and entering the atmosphere. When gaseous water is cooled it often condenses.?
These reverse processes are both part of the water cycle
Process of water turning into vapour?
Water most often becomes vapor when it is heated up. As water is heated up, its molecules vibrate faster. When water reaches its boiling point, the molecules are unable to remain a liquid and transition into a gas.

Is matter made out of solid liquid gass?
Matter is a combination of atoms, often molecules, that are in a solid, liquid, or gas phase.

How does decreasing the temperature affect the volume of a gas?
The molecules will not collide as often with the walls decreasing the volume

What influence gas molecules colliding?
The more often gas molecules collide the closer the particles are, this means that there is a very high volume in the space where the gas is located. Gas will expand when put into a large area in a process called diffusion.
How does condensation differ from boiling?
Both are the process of water changing state: first condensation is changing from vapor to liquid and evaporation is from liquid to a gas.
How does convection of heat take place in liquids and gases?
The molecules get heated up ,gain energy and move to a new location thus transmitting heat from one part of the liquid to another.Similar things occur in gases. In the place being heated, the particles move more quickly because the heat energy is converted into kinetic energy in the particles. Faster moving particles collide more often and with more force and so they spread out, becoming less dense. Less dense fluids float on denser fluids so the heated particles start to rise. This has two effects. Firstly, denser, colder liquid cones in to replace the risen fluid, which can also be heated and rise. Also, the hotter, risen and more energetic particles start to transfer some of their energy to the colder fluid around them. This sets up a CONVECTION CURRENT of fluid rising where it is heated, spreading out at the top and falling back down in the colder parts of the fluid. and moving along the bottom to replace the rising warmed fluid. This carries the heat to the whole of the fluid.
Why does air expand when it is heated?
The molecules of any fluid (including that of air) move faster when the fluid is being heated, because a result of increased kinetic energy (this energy is gained and increased because of increasing heat transfer rate or heat energy transfer). (note that heat transfer rate increase by a constant multiplied by temperature change between the initial and final temperature of the gas/any fluid in question). As a result of this molecular speed and kinetic energy increase, the molecules collide (with each other) more often as the temperature increases. The collisions make the molecules move far and further apart from each other (due to momentum), needing an increased volume/space to cantain them.
