Question

The melting point and the freezing point for all substances are always equal.

• A. True
• B. False

Answer 1

The correct option is A True

1. Melting point and freezing point describe the same transition of matter.
2. Freezing is the transition from liquid to solid and melting is a transition from solid to liquid.
3. In freezing, you have to take energy in the form of heat out of the water, and for melting we need to give energy in the form of heat to ice.
4. So melting points and freezing points for all substances are always equal.

Hence, the given statement is True.
