Hydrocarbon X is currently collected at the lower of two outlets in a fractionating column.
| Measurement | Temperature in °C |
|---|---|
| Boiling point of X | 170 |
| Lower outlet | 155 |
| Higher outlet | 105 |
An operator increases the temperature throughout the column by 25 °C without moving either outlet. The operator claims that X will still be collected at the lower outlet.
Explain whether the operator's claim is correct and where X will be collected after the temperature is increased.
