| What happens when you heat a solid liquid or gases? | Leating a solid , liquid or gas will usually just cause its temperature to increase. |
| What happens when enough heat is added to a solid? | However, if you add enough heat, then the substance will change state. |
| What happens when enough heat is added to liquid? | It will change its state to a gas. |
| What is melting? | Melting is the process in which heat causes a solid to change into a liquid. |
| What is the melting point? | A substance is solid below its melting point and molten [a melted liquid ] above it. |
| What is evaporation? | Evaporation is the process in which heat causes a liquid to change into gas. |
| What is sublimation? | Most substance change from solid to gas in two stages first they melt and then they evaporate. |
| What is boiling? | Boiling is a special case of evaporation. |
| What is the boiling point? | The boiling point of a substance is the temperature at which it changes from a liquid into a gas. |
| What is the boiling point of a substance? | The boiling point of a substance is the temperature at which it change from a liquid into a gas. |
| What is freezing? | Freezing occurs when heat is lost and a liquid change into a solid. |
| How is snow formed? | Snow is another formed of ice. |
| What is the opposite of freezing? | Freezing is the opposite process to melting and so freezing and melting occur at exactly the same temperature. |
| What is condensation? | Condensation occurs when a gas loses heat and change into a liquid. |
| What is steam? | Steam is water vapour that has condensed to form a cloud of tiny but visible liquid water droplets in the air. |
| What does heat do to the particles in a solid? | Heat adds energy to the particles in a solid , making them vibrate faster. |
| Why do clothes dry on a clothes line and why do they dry faster on hot days? | That's why clothes on the line eventually dry , even on cold days, on hot days, clothes dry faster because more water particles have enough energy to break free. |
| What happens to a substance if enough heat is removed from them? | A substance might change state if sufficient heat is removed from it. |
| What is the freezing point? | The freezing point is the temperature at which a liquid change into a solid. |
