The temperature at which a liquid boils and changes rapidly into a gas is called its boiling point.

The correct option is A True

The constant temperature at which a liquid starts changing into its vapour state is boiling point​.

• By increasing temperature, solids particles gain energy and vibrate vigorously.
• This allows the particle to move faster and intermolecular forces also increased and change to a liquid state.
• Again, on increasing temperature, the liquid particles move faster and change to the gaseous state.

So, the above statement is true.
