A pipeline operator records the boiling points of two hydrocarbons being considered for storage.
| Hydrocarbon | Boiling point |
|---|---|
| R | 42 °C |
| S | 198 °C |
Which conclusion about the molecules follows from these measurements?
The boiling points do not indicate which molecules are larger.
The molecules in S are larger than the molecules in R.
The molecules in R are larger than the molecules in S.
The molecules in R and S are the same size.
