# Changes in States of Matter ## Objectives - Define temperature. - Describe what happens to a material when it changes its state. - Give examples of changes in states of matter. ## Temperature Temperature is the measurement that tells how hot or cold a material is. When a material's temperature changes, its state may change. ## Changes in State Changes in state refer to the physical changes that matter undergoes when it transitions from one state (solid, liquid, or gas) to another. ## Melting Melting is the process by which a solid is heated and transformed into a liquid. This occurs when the temperature of the material reaches its melting point. ### Examples of Melting - Melting of a wax candle - Melting of an ice cube ## Freezing Freezing is the process by which a liquid is cooled and transformed into a solid. This occurs when the temperature of the material reaches its freezing point. ### Examples of Freezing - Freezing of juice into popsicles - Freezing of water into ice ## Evaporation Evaporation is the process by which a liquid is heated and transformed into a gas. This occurs when the temperature of the material reaches its boiling point. ### Examples of Evaporation - Boiling of water - Drying of clothes ## Condensation Condensation is the process by which a gas is cooled and transformed into a liquid. This occurs when the temperature of the material reaches its condensation point. ### Examples of Condensation - Formation of dew drops - Formation of clouds ## Question What are other examples of matter changing its state? ## Check for Understanding - What is temperature? - What happens to a material when it changes its state? - What are examples of changes in states of matter?
