| Question | Answer |
|---|---|
| What is melting? | Melting is the change from a solid to a liquid,when solids are heated the particles gain energy and vibrate faster,more heat is supplied the more the particles vibrate,the forces holding the particles together break and they separate,the solid is melting |
| What is the melting point? | The melting point is the temperature at which the solid changes. |
| What is evaporation? | Evaporation is when a liquid changed to gas as the surface of the liquid,,evaporation occurs when particles on the surface of the liquid build up enough energy to break free as gas,evaporation can happen at any temperature,even room temperature. |
| What happens when liquids are heated? | The particles gain energy and move faster. |
| What is boiling? | Boiling is when a liquid changes to a gas,when a specific temperature is reached,particles of gas form throughout the liquid,when bubbles have formed throughout the liquid,it is boiling,boiling is quicker than evaporation. |
| What is a boiling point. | Boiling occurs at a set temperature known as the boiling point,different liquids have different boiling points,e.g for water the boiling point is 100 Celsius |
