| Question | Answer |
|---|---|
| What is matter? | Something that has volume and mass. |
| What isn't matter? | Energy. |
| What is Volume? | The amount of space something takes up. |
| What is Mass? | Amount of stuff packed in an object. |
| What is the Law of Conservation of Mass/Matter? | Matter stays the same even when it changes form, Mass can't be created or destroyed. |
| What is Weight? | The gravitational pull. |
| What is the difference between Mass and Weight? | Mass is the amount of stuff packed in an object, and weight is how heavy something is. |
| What is Density? | How tightly something is packed. |
| Does the amount of something present affect its density? Explain. | The density does not change as the amount of the substance present changes. |
| What is Buoyancy? | The ability to float on water or air. |
| What are three properties of a solid? | Solids are fixed shapes, solids can't be compressed, solids have high density. |
| What are three properties of a liquid? | Viscosity, boiling point, and melting point. |
| What are three properties of a gas? | The temperature of a gas, the pressure of a gas, and volume occupied by a gas. |
| Draw the particles in a solid. | |
| Draw the particles in a liquid. | |
| Draw the particles in a gas. | |
| What is plasma? | Plasma is when gas get's very hot. |
| What is Melting? | Melting is when a solid goes to liquid. |
| What is Freezing? | Liquid to solid. |
| What Evaporation? | Liquid to vapor. |
| What is Condensation? | Gas to liquid. |
| What is Sublimation? | Solid to gas. |
| What is Deposition? | Gas to solid. |
| What is Vaporization? | Liquid to gas. |
| What's the difference between boiling and evaporation? | Boiling is bulk phenomenon and has bubbles, evaporation is surface phenomenon and doesn't have bubbles. Evaporation happens at room temperature, boiling you have to heat it up. |
| Describe how adding or subtracting energy from matter changes its phase. | It causes the particles to move faster or slower. |
| What's the difference between a Physical Property and a Chemical Property? | The physical property is a solid so you can measure it without changing it, but a chemical property is harder to measure so you have to change it. |
| List some physical properties of matter. | Density, color, and hardness. |
| List some chemical properties of matter. | Flammability, toxicity, and acidity. |
| Be sure you know the properties we covered in class (malleability, solubility, etc.) | Malleability is when metal is hammered into thin sheets of metal, solubility is when two substances attract and combine. Example: salt to water. |
