The 3 States of Matter!!!!!
Transcript of The 3 States of Matter!!!!!
Of Matter!!! Gases Melting Freezing Solids have definite volumes and a definite shape. The particles of a solid are very closely packed together. Liquids have definite volumes but no shape of their own. Liquids take the shape of their containers and if the is no container then they spread freely. Gases can change volume very quickly, particles of a gas move at high speeds in all directions. like liquids they also take the shape of their containers. Meliting is the change in state from a solid to a liquid in most pure substances, melting occurs at a specific temperature called the melting point. At its melting point the particles of a solid are vibrating so fast they break free from their fixed poistions. Is the change of state from a liquid to a solid, at its freezing temperature the particles of a liquid are moving so slowly that they begin t form regular patterns. Matter can be classified as solids, liquids, or gases. They are defined by the way they hold their volume and shape. Solid Liquid Gas Solid Some examples of solids are a diamond ring, some Di, and a rubix cube. Apple juice, orange juice and water are some examples of liquids. Some examples of gases are the air inside a hot air balloon,and the fire that comes of the stove burner. These are both gases. The changes of states of matter are metting, freezing, vaporization and sublimation. Some examples of melting are chocolate melting, ice cubes melting, and ice ream melting. An example of freezing is when you put a liquid such as water in a cold area and it begins to form a solid. Vaporization Vaporization is the change from a liquid to a gas. Vaporization takes place when the particles in a liquid gain enough energy to form a gas. An example of vaporization is when water boils to a certain temperature and it evaporates. Condensation Condensation is the change from a liquid to a gas, it is also the opposite of vaporization.
Condensation occurs when particles in a gas lose enough thermal energy to form a liquid. An example of condensation is what happens on the side of your water bottle. Atoms An atom is the basic particle from which all elements are made. Examples:
Calcium Elements Evaporation Vaporization that takes place only on the surface of a liquid. An example of evaporation is when you leave some water outside on a sunny day and it disappears. examples: A pure substance Carbon
chlorine Compound When two atoms combine. Examples:
Carbon Dioxide Gas Homogenous & Heterogeneous Homogenous mixtures are so evenly mixed that u cant see or separate the different parts Lemonade is an example of a homogenous mixture In a Heterogeneous mixture the particles is when u can see and easily pick out the different parts. Fruit salad is an example of a heterogeneous mixture. Mass And Volume We use density to find mass and volume by dividing mass by volume. This picture shows the formula for density. Potential and Kinetic Energy Potential energy is energy
that is stored in a person or object. This girl about to shoot an arrow is an example of potential energy Kinetic Energy is the energy of moving matter. An example of kinetic energy is this man running. Types of Energy Examples 1. Sound Energy - When u are shouting at a friend its Sound Energy
2. Thermal Energy- when you heat food with a heat lamp you are using thermal energy
3. Electrical Energy- When you turn on a light you are using electrical energy
4. Nuclear Energy- when matter is changed to energy at a power plant nuclear energy is produced
5. Chemical Energy- when you eat breakfast it provides chemical energy to you
6. Mechanical Energy - mechanical is the type of energy that leaves a power plant This is a picture of sound energy. This picture shows how food gives us chemical energy Motion, Speed, Direction Speed is distance divided by time. The speed for my egg drop was 9 feet per second. Motion is the movement of an object. The motion of my parachute was very slow. Direction is like the way my parachute went down during the eggs drop. Types Of Energy Thermal- Total kinetic energy of all the atoms that make up an object. Sound- Energy that travels in waves though matter from a vibrating object. Electrical- Energy of moving electrons. Nuclear- energy released in a nuclear reaction Chemical- Energy that is stored in the bonds between atoms that make up compounds. Mechanical- energy of an object that is moving or has the potential to move. http://www.youtube.com/watch?v=s-KvoVzukHo&feature=player_detailpage Watch this video for more info about solids, liquids, and gases!
