| Question | Answer |
|---|---|
| Define specific heat capacity. | The amount of energy required to heat 1 kg of a substance by 1°c |
| What is the formula for specific heat capacity? | E=MCΘ |
| What does the E stand for? | Energy required |
| What does M stand for? | Mass |
| What does C stand for? | Specific heat capacity |
| What does Θ stand for? | Temperature change |
| Why would materials in heaters have high specific heat capacities? | Because the materials could store a lot of heat energy |
| How is water's specific heat capacity used? | It is high so is useful for heating buildings when pumped around by pipes |
| What materials are used in electric storage heaters and how are they used? | Materials with high specific heat capacity such as concrete or bricks, so they can store energy at night and release it during the day |
| Why would you want to store the heat at night? | Because electricity is cheaper at night |
| What is one benefit of oil based heaters over water? | Oil has higher boiling point so can reach higher temperatures more safely than water heaters |
| What would be one reason why oil based heaters are worse than water based heaters? | Because water as a higher specific heat capacity |
