Example of solid changing toliquid:when you take an ice and put it to thaw out it changes to water (liquid) and is the same for liquid to solid; you freeze water(liquid) and it turns to ice (solid)
It is called melting when a solid turns into a liquid
When a solid turns to a liquid, such as ice turning to water, it is commonly called melting. The solidification of a liquid to a solid is called freezing.
LIQUDIFCATION!!!!!!!! Change of phase; the process is called melting.
Simply, the melting point. Think of an ice cube. The melting point is the temperature at which the ice cube MELTS into a liquid.

solid before it melts?
Filter paper is a poor material on which to powder a solid before introducing it into a melting tube. Why ?
It would be solid before it reached the melting point. If it is liquid, it has already reached the melting point.
Freezing is usually when something is turning cold, and solid. Melting is usually when something is turning hot, and into a liquid. Sometimes, depending on chemicals, their can be exceptions to those.
It turns from a solid to a liquid
The physical change of a solid to a liquid at the melting point called melting.
It burns before melting.
Melting is the change from solid to liquid.
