Name _______________________________Teacher _________ Period _____ Date _________ 1. Know the definitions to the following vocabulary terms or be able to identify examples of. Vaporization Point – the temperature at which a liquid heats up and becomes a gas Condensation Point – the temperature at which a gas becomes a liquid Melting Point – the temperature at which a solid becomes a liquid Freezing Point – the temperature at which a liquid changes to a solid Thermal Energy – energy that the particles of a substance has, heat energy Sublimation – when a solid turns directly into a gas Viscosity – the resistance of a liquid to flowing Substance – a single kind of matter that has distinct physical and chemical properties Matter – Anything that has mass and takes up space Physical Property – a characteristic of a substance that can be observed without changing the substance into something else Chemical Property – a characteristic observed when a substance interacts with another substance Physical Change – a change that alters the form or appearance of a material but does not make the material into another substance Chemical Change – a change in matter that produces new substances with properties different from the original substance 2. Be able to list the 4 states of matter as discussed in class and on your notes. (See “Describing Matter Notes”) Solid, liquid, gas, plasma 3. Know the 3 properties of solids as discussed in your notes. (shape, volume, particles) . (See “Describing Matter Notes”) Definite shape, definite volume, particles of a solid are tightly packed 4. Know the 3 properties of liquids as discussed in your notes. (shape, volume, particles) (See “Describing Matter Notes”) No definite shape, definite volume, particles are more loosely packed than a solid so they may slide over each other 5. Know the 3 properties of gases as discussed in your notes. (shape, volume, particles) (See “Describing Matter Notes”) No definite shape, no definite volume, particle travels very fast and are farther apart 6. Know how a plasma is different from a gas. (See “Describing Matter Notes”) No definite shape, not definite volume, electrically charged Examples of plasma – lightning, stars, flurescent lights, neon lights, plasma tvs, plasma balls Name _______________________________Teacher _________ Period _____ Date _________ 7. Be able to explain the diagram on your notes about solids, liquids and gases and all the different temperature points listed on them (freezing, melting, etc…). (See “Describing Matter Notes”) Rise in temperature – gains energy Melting Point Solid Freezing Point Vaporization Point (Boiling or Evaporation) Liquid Condensation Point Gas Decrease in temperature – loss of energy 8. Be able to identify examples of physical and chemical properties. Be able to identify examples of physical and chemical changes. (See “Changes in the Properties of Matter – Physical and Chemical”, Worksheet on Physical and Chemical Properties and Identifying Changes 9. Know the 4 identifiers or evidence that a chemical change is happening. (See back side of worksheet “Changes in the Properties of Matter – Physical and Chemical”and the Mystery Powder Lab) Formation of a gas Color change Temperature change Precipitate forms
