it melts
All forms of matter have the three basic forms of solid - liquid - gas. Therefore, every solid can eventually be formed into a liquid by heating it up.
"Liquefy" means to make or become liquid, usually by heating or applying pressure to a solid substance.

One example of a liquid that turns solid upon heating is butter. When heated, butter transforms from a liquid state to a solid state as it reaches its melting point, which is typically around 32-35°C (90-95°F).
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.
I think it's liquid because heating it will make it evaporate.
Salt can be changed from solid to liquid by heating it to its melting point, which is 801°C. Once it reaches this temperature, it will turn into a liquid. However, salt cannot be changed directly from liquid to gas through a process like evaporation; instead, it will first need to be heated to a very high temperature to turn it into a gas.
To turn a liquid into a solid you have to freeze it. To turn a gas into a solid you must first turn it into a liquid, then freeze it.
Usually heating the liquid will allow more solid to be dissolved. This not always the case though.
Any liquid can turn into a solid at the correct temperature.
When a solid turns into a liquid due to heating, it is called melting.
