Solution

The correct option is A True
Latent heat of fusion is the heat energy that is absorbed by solid without showing any rise in temperature during phase change at melting point. Since this energy is used for overcoming the inter-particle force of attraction, the kinetic energy of the particles remains constant and hence there is no rise in temperature.

Q. Latent heat of fusion is the heat energy that is absorbed by the solid without showing any rise in the temperature.

Latent heat of fusion (or vaporisation) is the heat energy that is absorbed by solid (or liquid) without showing any rise in temperature.

It has been observed that temperature remains constant till all solid melts into liquid. The heat supplied is used for changing a solid state into its liquid state by overcoming the particle-particle attraction force. The solid substance absorbs heat energy without showing any rise in temperature. This heat energy is called latent heat. The amount of heat required to convert a unit mass of a solid into its liquid state, without a change in temperature (i.e. at its melting point) is called the latent heat of fusion.EXPLAIN

define the term:-heat of fusion. why amorphous solids have definite heat of fusion??

As amorphous solids are isotropic they will have same values of physical quantities such as, heat of fusion in all directions.

the answer provided by the mn expert is wrong as amorphous solids do not have a definite heat of fusion.

Using the latent heat of fusion how can a solid turn into a liquid without the change in temperature?
