In a calorimetry experiment, a student burned 0.50 g samples of five different alcohols to heat 100 cm3 of water. The temperature rise produced by each alcohol was recorded.
| Alcohol | Number of carbon atoms in one molecule | Temperature rise of water in ∘C^\circ\text{C}∘C |
|---|---|---|
| Methanol | 1 | 12.0 |
| Ethanol | 2 | 19.5 |
| Propanol | 3 | 24.0 |
| Butanol | 4 | 26.5 |
| Pentanol | 5 | 28.0 |
Draw a graph of the temperature rise of water against the number of carbon atoms in one molecule of the alcohol.
