## How do I calculate how much heat I need?

**To calculate the energy required to raise the temperature of any given substance, here’s what you require:**

- The mass of the material, m.
- The temperature change that occurs, ΔT.
- The specific heat capacity of the material, c (which you can look up). …
- Here is a source of values of c for different substances:
- Q=m×c×ΔT.
