Question

The boiling point of a liquid is tested at 10 different pressures, from 0.5 to 1.4 atmospheres. The results of the tests show that there is a nearly constant increase in boiling point for each increase in pressure. Which conclusion is reasonable based on this information?(1 point)
Responses

A boiling point at 1.5 atmospheres could be predicted fairly well.
A boiling point at 1.5 atmospheres could be predicted fairly well.

A boiling point at 1.5 atmospheres could not be predicted with any certainty at all.
A boiling point at 1.5 atmospheres could not be predicted with any certainty at all.

A boiling point at 15 atmospheres could not be predicted with any certainty at all.

Answer 1

A boiling point at 1.5 atmospheres could be predicted fairly well.

Reason: 1.5 atm is just beyond the tested range (0.5–1.4 atm) and the data show a nearly constant (linear) increase, so a small extrapolation is reasonable. Predicting at 15 atm would be far outside the data and unreliable.
