2. Kinetic Theory of Matter Matter is made up of vibrating particles Temperature A measure of how hot or cold a substance is a gain or loss of energy can cause a substance to state. HEATCHANGE

3. CHANGING THE STATE OF MATTER OF A SUBSTANCE SOLID LIQUID: Heat energy is by the solid. kinetic energy of particles. Particles begin to around each other more freely. Melting Point – While the substance is melting (change in state) temperature will. MELTING absorbed Increasing move the temperature at which a substance changes from a solid to a liquid. remain the same

4. CHANGING THE STATE OF MATTER OF A SUBSTANCE LIQUID GAS: Heat energy is by the liquid. kinetic energy of particles. Particles move even further apart and begin to around each other more freely. Boiling Point – While the substance is boiling (change in state) temperature will. EVAPORATION absorbed Increasing move the temperature at which a substance changes from a liquid to a gas. remain the same

5. CHANGING THE STATE OF MATTER OF A SUBSTANCE GAS LIQUID: Heat energy is by the gas. The particles and Condensation Point – During the change in state, temperature will CONDENSATION released slow downmove closer together. the temperature at which a substance changes from a gas to a liquid. remain the same

6. CHANGING THE STATE OF MATTER OF A SUBSTANCE LIQUID SOLID: eEnergy is by the liquid. Particles move even more. Freezing Point – During change in state, temperature will. Freezing Point = Boiling Point = FREEZING released slowly the temperature at which a substance changes from a liquid to a solid. remain the same Melting Point Condensation Point
