Question

A substance X has a melting point of 80 degree C. What is the freezing point of the substance

Answer 1

Answer:

-20°C because if it would be 100 then it's freezing point would be 0°C

Answer 2

Answer:

The freezing point of the substance is 80°C.

Explanation:

We have seen that the melting and freezing point of water is 0°C. This tells us that melting is just a process in which latent heat of fusion is required to loosen up the bonds that exist amongst the molecules. A substance X has a melting point of 80°C, which means, the freezing point of the substance will be 80°C. X can lose the latent heat to solidify.

Conclusion:

The freezing point of the substance X is 80°C.
