Boiling Point | MCQs

Explanation

• The freezing point of water is 0°C (zero degrees Centigrade). 
• The boiling point of water on the Centigrade scale (also known as the Celsius scale) 100°C (one hundred degrees Centigrade).

Explanation

In the Fahrenheit scale:

• The freezing point of water is 32°F
• The boiling point of water is 212°F

Explanation

The boiling point is the temperature at which a pure liquid changes state from liquid to gas at standard atmospheric pressure.

Key Points:

• The melting point is the temperature at which a solid changes state to a liquid.
• The freezing point is the temperature at which a liquid changes state to a solid.

Explanation

• The initial temperature of a liquid does not affect its boiling point.
• The boiling point is the temperature at which a liquid changes state to a gas at a given pressure.
• It is a physical property of the substance itself.
