## What are gas behavior laws?

Any of several statements of physics and chemistry relating to the behavior of gases: such as Boyle's law and Charles' law.

### Describe Boyle’s law and Charles’ Law and explain an example of each.

Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. Example: It's a warm sunny day. You are careful not to pump in too much air into your inflatable raft. In spite of that, if you leave it outside the pool, it could well pop as air inside it heats up and expands. The solution is to pump it while the raft is in the pool; then, leave it in the pool until you actually start using it. Deflate it immediately after use. Boyle’s law states that the pressure exerted by a gas is inversely proportional to its volume at a constant temperature in a closed system. This means that as the pressure increases, the volume decreases and vice versa. Example: a spray can, like spray paint or an air freshener. Inside the can, there is an intense build-up of pressure and a minimal amount of volume in the can. When you press down on the trigger, it opens up a hole at the top, allowing some of that pressure out which creates the colored paint or the smell. With the temperature staying the same throughout, the intense pressure is varied indirectly with the minimal amount of volume allowed in the spray can showing that this is an example of Boyle's law.

### Condensation

The conversion of a vapor or gas to a liquid.

### Deposition

The phase change from gas to solid.

### Evaporation

The process of turning from liquid into vapor.

### Kinetic energy

Kinetic energy is the energy an object possesses due to its motion.

### Sublimation

Sublimation is the term for when matter undergoes a phase transition directly from a solid to gaseous form, or vapor, without passing through the more common liquid phase between the two.

### Physical change

A usually reversible change like ice melting.

### What happens when you remove thermal object to the object’s state of matter

The matter particles in matter start moving slower

### Vaporization

The phase transition of a substance from the liquidphase to the gasphase.

### Potential energy

Is that energy which an object has because of its position.

### Explain how are mass and energy conserved in a Change of State of Matter

Mass: mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

Energy: neither be created nor destroyed; rather, it can only be transformed from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all the chemical energy that is expended in the explosion, one will get the exact amount of kinetic energy that is generated.
