The table shows the specific heat capacity of four substances.
| Substance | Specific heat capacity / J g-1 °C-1 |
|---|---|
| Water | 4.2 |
| Ethanol | 2.4 |
| Sand | 0.80 |
| Copper | 0.39 |
Calculate how many times more energy is needed to raise the temperature of 1 g of water by 1 °C than to raise the temperature of 1 g of sand by 1 °C.
