Question

define melting point

Answer 1

Melting point is the temperature at which a solid becomes a liquid at normal atmospheric pressure. A pure substance under standard condition of pressure has a single reproducible melting point.

HOPE it helps!!!!

Answer 2

Hey !!

The temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point.

When a solid melts, its temperature remains the same. Melting point of those substances which contract upon melting reduces on increasing pressure.

Now, on the other hand melting point of those substances which expand upon melting increases with increasing temperature.

Good luck !!
