Question

What is the difference between freezing point and boiling point?

Answer 1

The freezing point of a substance is defined as the temperature at which matter or a substance is changed from its liquid state into solid... . Water, which is a pure substance,has the same melting and freezing points.

Answer 2

BOILING POINT:

• The 'boiling point' of a compound or a substance is level of temperature at which the "vapour pressure" of liquid is equal to the pressure surrounded by the liquid where the liquid is converted into vapour.
• The boiling point varies from one substance to another based on its 'environmental pressure'.
• For example, the 'boiling point' of 'water' is 100 degree Celsius.

FREEZING POINT:

• The 'freezing point' of a substance is the level of temperature at which a 'liquid' is converted into 'solid'.
• In case of mixtures, the freezing point is comparatively lower than the boiling point.
• An increase in pressure increases the freezing point as the freezing point and pressure are 'directly proportional'.
• For example, the 'freezing point' of 'water' is 0 degree Celsius.
