To turn from a solid to a liquid it must reach it's melting point by heating up. Examples: ice to water, rocks to magma. Every thing melts at a different temperature.
Heat them.
The process of melting.
heat
liquids turn into gas and solids don't and gas evaporates
with some you can ex) water can turn into ice
All solid can be liquified if the temperature is high enough.
Liquids can through evaporation, and solids can through combustion.
When a liquid looses enough energy (heat), it turns into a solid.
Solids to Liquids (Melting) Liquids turning back into a Solid (Freezing) ((SCF))
solids and liquids
Solids turn into liquids at their melting point.
Both liquids and Solids have definite volumes
