it depends on what solid you are talking about, every element has different melting points
Solid changes to liquid when a substance reaches it's melting point. For example, water's melting point is 0 degree celcius.
change of a liquid to a solid
The change from liquid to solid is called freezing.
Sure, change from solid to liquid is a physical change
when ice was solid change liquid because sun was very hot. ice will change liquid change back solid again
change of a liquid to a solid
Freezing is the change in state from liquid to solid.
The change in state from a solid to a liquid is called melting.
the liquid to solid evolution
a loss in energy cause the change from liquid to solid like-wise a rise in energy causes a change from solid to liquid.
Decreasing the temperature a liquid become a solid.
The change of state from solid to liquid is called melting.
