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. HEAT CHANGE

CHANGING THE STATE OF MATTER OF A SUBSTANCE SOLID LIQUID: MELTING 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 . absorbed Increasing move the temperature at which a substance changes from a solid to a liquid. remain the same

CHANGING THE STATE OF MATTER OF A SUBSTANCE LIQUID GAS: EVAPORATION 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 . absorbed Increasing move the temperature at which a substance changes from a liquid to a gas. remain the same

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

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