A student investigated the energy released when different alcohols were burned using a spirit burner. Their results are shown in the table below.
| Alcohol | Mass of alcohol burned / g | Temperature rise / °C |
|---|---|---|
| Methanol | 0.45 | 15 |
| Butanol | 0.25 | 15 |
Explain, using only the information in the table, why butanol might be the better fuel.
