Question

When a solid melts , why does the temperature remain constant and what happens to the arrangement of particles?please answer

Answer 1

Answer:

latent heat

Explanation:

it is the heat absorbed without ride in temperature.occurs only during change of state.

Answer 2

Answer:

When a solid melts, the temperature of the solid remains constant and does not rise. This phenomenon is called Specific Latent Heat of Fusion.

During this time, the heat absorbed by the solid is used to increase the inter molecular spaces between the particles and weaken their inter molecular forces in order to change the state of the matter.
