Question

define the following a melting and melting point B boiling the boiling point c sublimation and sublimation.​

Answer 1

On the Celsius scale, H 2O has a melting point of 0°C and a boiling point of 100°C. At 0°C, both the solid and liquid phases of H 2O can coexist. ... Other substances have melting points and boiling points as well. Second, the temperature of a substance does not change as the substance goes from one phase to another

Answer 2

Explanation:

Melting -When solid convert into gas by increasing temperature is called melting.

Melting point -The temperature in which solid starts melting is called melting point.

Boiling -When liquid start changing into gas by increasing temperature is called boiling.

Boiling point -The temperature in which liquid start converting into gas is called boiling point.

Sublimation -The process in which gas directly convert into solid or solid directly convert into gas on increasing temperature is called sublimation.
