Question

When heat is supplied by a gas burner with small flame to melt ice then the temperature of ice during melting *

Increases very slowly
Does not increase at all
Option 3 first it remains constant and then increases
Increases to form liquid water


plz give the answer if you know ! spam = 20 answers report ! ​

Answer 1

Correct option is B does not increase at all.

Explanation

To turn solid ice into liquid water we have to push the water molecules inside further apart and break apart the framework (or crystalline structure) that holds them together. So while ice is melting (during the change of state from solid water to liquid ice) all the heat energy we supply is being used to separate molecules and none is left over for raising the temperature.The heat needed to change a solid into a liquid is called the latent heat of fusion.

I hope it will help you.

Answer 2

Answer:

Does not increase at all

Explanation:

During melting temperature of ice does not change at all because the heat is used to over coming the particle attraction force which in turn keep the temperature constant.
