Question

What is the name of the process when a liquid changes into a gas?

Answer 1

Phase change:

• When there is a phase transition from a liquid phase to the gaseous phase, this process is known as Vapourization.

Vapourization:

• Vapourization can occur either by boiling or evaporation.
• Evaporation occurs more rapidly in liquids as a liquid becomes warmer due to the increase in vapor pressure.
• Boiling occurs when the vapor pressure of the liquid is equal to the atmospheric pressure.
• The temperature at which liquids begin to boil is known as the boiling point.
