Gases

There are gases you can see and some that you cant. For instance a gas you encounter daily is the atmosphere. You can see water vapor or steam but you can see air. The Kinetic Particle Theory of Gases describe and explain the behavior of gases.

• They are in constant random motion and are always colliding with themselves or the container they are in
• They have what are called elastic collisions and they never lose energy because when they hit each other there energy is transferred
• Gas particles don't stick together; they aren't attracted or repelled  by each other, they floe freely 
• Different particle move at different speeds and speed is related to temperature because heat gives the particle energy and cold decreases their energy
• Pressure is related to how many times the particles hit each other

Particles will move in a straight line until they hit another particle and deflect into another direction. When they collide they have an elastic collision which mean they bounce off each other and they never loss energy because when they collide the energy is transferred to the different particles. Gas particle don't stick together because they are constantly bouncing off eachother. When the temperature is increased the particle move faster and when the temperature is decreased the particles move slower. The pressure is related to the frequency and impact that the particles to each other and their container. Gases have lower densities because the particles are more spaced out then in a liquid or solid. Gas particle also like to travel from areas of high concentration to areas of low concentration. This is because the particles flow freely with out attracting or repelling each other. The can move pass each other easily to spread out.The particles can easily compress and expand because there is a lot of space between gas particles unlike the particles in water or a solid.
