Section 1


 * 1.** //The three assumtions of kinentic theory are as follows: 1.) all matter is composed of small particles (atoms, molecules, and ions). 2.) These particles are in constant motion. 3.) These particles are constantly colliding with each other and the walls of their container.//


 * 2**//. The movement of particles in soilids from thermal energy in them that causes them to viberate. In a liquid the particles are moving more freely then in a soild thus allowing them to flow and take the shape of their container. The particles in a gas state have enough energy to overcome the attractions between them and can spread apart or contract to fill a container because, they have no fixed vilume or shape.//


 * 3.** //When particles finally gain enough kinetic energy to slip out of place of their ordereded arragments it is called the melting point.//


 * 4.** //At the boiling point of a substance particles are pushed down and kept from escaping because of the external pressure acting on the liquid's surface.//

__Section 2__


 * 1.**//The two forces that act upon an object that is water are the objects weight and the buoyant force.//


 * 2,** //The reason that heavy boats can float in water is because thhat the ships hull is filled with air. This also means that the overall denisity of the stell boat and air is less than the density of the water that the boat is floating in.//


 * 3.** //Using Pascal's Principle the reason that the mustered will come out the end of the bottle is because that the pressure applied to a fluid is transmitted evenly throughout the fluid. So when you squeeze the mustered bottle and apply pressure to the mustered bottle and the pressure is transmitted to the mustured so it then comes out the end of the bottle.//


 * 4.** //When you use Bernoulli's Principle it tells you that if you blow air across a pice of paper the paper will go up, because the air your blowing over the paper has a greater velocity than the air under it and the pressure pushing down on it is lower then the other which makes the paper go up cause the force from below it.//


 * 5.** //The reason the ballon wouldn't float is because the air in the ballon is more dense than the air around it. If the ballon was filled with hellium it would probally float given that helium is so much less dense.//
