In a laboratory investigation, a student burned exactly 1.0 g samples of different alcohols to heat 100 cm3 of water in a copper calorimeter. They recorded the temperature rise of the water for each alcohol.
| Alcohol | Number of carbon atoms in one molecule | Temperature rise of water in °C |
|---|---|---|
| ethanol | 2 | 18.5 |
| propanol | 3 | 24.0 |
| butanol | 4 | 28.0 |
| pentanol | 5 | 31.0 |
| hexanol | 6 | 33.0 |
Draw a graph of the temperature rise of the water against the number of carbon atoms in one molecule of the alcohol.
