Question

At atmospheric pressure, the freezing point of water is ___________ and boiling point of water is _______.

• A. 50 °C; 100 °C
• B.
  0 °C; 10 °C
• C. 100 °C; 0 °C
• D. 0 °C; 100 °C

Answer 1

The correct option is D 0 °C; 100 °C

Freezing point is the temperature of a liquid at which it changes its state from liquid to solid at atmospheric pressure.
For example- Water converts into ice at 0 °C at atmospheric pressure.

Boiling point is the temperature of a liquid at which it changes its state from liquid to gas at atmospheric pressure.
For example- Water converts into steam at 100 °C at atmospheric pressure.
