Facets:
value: in the gas phase
type: TEMPORAL
Source sentences:
text: This causes the boiling point of the mixture to rise, which results in a rise in the temperature in the vapor, which results in a changing ratio of A : B in the gas phase (as distillation continues, there is an increasing proportion of B in the gas phase).
