Answer 2

There are some solids that can be changed into liquids by simply exposing them to sunlight.

• The conversion of a solid into a liquid is a physical change. It is a change of state.
• When a body attains a certain amount of heat and reaches a temperature at which the solid changes into the liquid state, then that temperature is called the melting point of the solid.
• The constant heat provided by the sunlight helps the solid attain the melting point.
• An example of such a change is ice melting into water.
• Cold air, moonlight and moisture cannot provide heat to such solids and that is why do not change them into liquids by exposure.
