The process in which a liquid changes to its gaseous state at a constant temperature is called boiling.
Therefore, the given statement is true.
The process in which a liquid changes into its gaseous state at any temperature above its boiling point is called evaporation.
The fixed temperature at which a liquid state changes into gaseous state, due to the process of vaporisation, is called :
The process that involves the change of state from liquid to its gaseous state at any temperature below its boiling point is called_________.
