At a processing plant, three hydrocarbon liquids are pumped separately through identical pipes. Each liquid is pumped at the same pressure and temperature for 1 minute. The table shows the volume transferred. The liquids contain hydrocarbon molecules of different average sizes.
| Hydrocarbon liquid | Volume transferred in 1 minute in dm3\text{dm}^3dm3 |
|---|---|
| J | 18 |
| K | 45 |
| L | 30 |
Use the results to explain the order of J, K and L from the least flammable to the most flammable.
Which hydrocarbon liquid has the highest boiling point? Explain your answer.
