Question

1. On increasing pressure the boiling point of pure water _____.​

Answer 1

Answer:

As the pressure applied to the liquid surface is increased, the energy needed for the liquid molecules to expand to gas phase also increases. Hence, a higher temperature is required to change liquid to gas phase. So, boiling point of liquid rises on increasing pressure.

Answer 2

Explanation:

The boiling point of pure water 99.97 °C (211.9 °F)
