Question

Explain the process of melting and latent heat of fusion

Answer 1

latent heat fusion

solid is converted into liquid

Answer 2

HLO MATE HERE IS UR ANSWER.

❤. PROCEDURE ❤

⭐. Take small ice cubes in a beaker. Insert the thermometer in the beaker.

⭐. Now start heating the beaker and note down readings of the thermometer every one minute till the ice completely melts and gets converted into water.

⭐. Before heating the temperature of ice is 0 degree C or less than 0degree C.

❤. OBSERVATION ❤

⭐. We will observe that the temperature of ice at the beginning is equal to or below 0 degree C.

⭐. If the temperature of ice is below 0 degree C , it goes on changing till it reaches 0 degree C.

⭐.When ice starts melting , we will observe no change in temperature though we are supplying heat continuously.

❤. EXPLANATION ❤

⭐. Given heat energy uses to break the bond (H2O) in ice and melts.

⭐. So , temperature is constant while melting.

❤. CONCLUSION ❤

⭐. This process is called melting . In this process heat converts solid phase to liquid phase.

⭐. The temperature of the substance does not change until all the ice melts and converts into water.

⭐. The heat given to melting is called latent heat of fusion.

⭐. The heat required to convert 1gm of solid completlg to liquid at constant temperature is called "latent heat of fusiom".
