Question

Define boiling point

Answer 1

Boiling point

• The temperature at which the liquid boils and changes into a gaseous state at atmospheric pressure.
• For example, water boils at 100°C to form water vapour.
• The boiling point of the liquid depends upon the pressure of the surrounding.
• When the liquid is at high pressure, it has a higher boiling point than the boiling point at normal atmospheric pressure.
• The boiling point of different liquids is different for a given pressure.
