Question

Define the following process involved in the change of state of a substance- vapourasation

Answer 1

1. Vaporization: It is a physical process in which a liquid changes into its vapor state at a constant temperature.
2. There are two ways in which a liquid changes into a vapor state.
   2.1. Boiling: The process of converting a liquid into its vapor phase at a constant temperature. The boiling point is the temperature at which a liquid boils. For instance, the boiling point of water is ${100}^{°}C$.
   2.2. Evaporation: is the process of converting water to water vapor. Unlike boiling, it occurs at all temperature ranges.
