Molten metal will solidify as its temperature decreases; that is, by cooling. Almost all metals are solid at room temperature. However, a metal like Mercury is normally a liquid, so changing mercury into a solid requires cooling to -40 degrees C.
WE KNOW THAT...
"When an object is heated then its inter-molecular distance increases."
{The inter-molecular distance of liquid is more than that of solid}
When metal is heated then the inter-molecular distance of metal increases and converts into molten metal and then this molten metal when cooled down then the inter-molecular distance decreases and then converts into solid.

When enough thermal (heat) energy is removed from the molten sample, to the state
where the macroscopic measurement of temperature decreases to values of less than,
for example, 660° C for aluminum, 961° C for pure silver, 1,770° C for platinum,
negative 38.9° C for mercury, 1,063° C for 24K gold, 1,084° C for copper, etc., the mean
intermolecular separation and mean molecular kinetic energy are both reduced to the
critical value where a distinct change of state takes place. The molten sample, which
formerly had no definite shape, takes on a definite shape in the manner of 'solids'.
Erudite, bourgeois observers refer to this process as 'solidification', whereas the less
sophisticated onlooker more commonly describes it as 'freezing'. The same identical
process may be observed at any time in the case of a sample of H2O that has been
cooled to a uniform temperature below 32° F (0° C).
It turns to a solid when it cools down
By cooling, normally with water.
by freezing
It cools.
Osmium is a solid metal at room temperature.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
Theoretically, anything can be changed from a solid to a liquid with enough energy added. Consequently, any gas can be changed into a liquid when enough energy is removed from it.
liquid to solid
Sublimation
Solidify...?
When purified solid metal is heated under very high temperature it changes to liquid metal .This liquid metal is called molten metal .
A metal is actually solid beforwe application of high heat,a metal becomes molten when the heat is high enough to enable breakage of bonds between molecules of the metal such that the molecules are free to move as in liqiud.so a molten metal becomes solid when molecules form bond again as in solid.
No. The solid state of a metal is more dense than its liquid state, so it sinks.
Igneous Rock
Dross - solid metal scum or debris floating on molten metal
No. It is a solid metallic alloy.
the outer core. the last answer was the inner core.. but im sorry to tell them that im doing this section in school currently and the OUTER core is made of molten metal. the inner is solid metal.
No. The inner core is composed of solid metal, mostly an iron-nickel alloy.
outer core
It is widely scientifically believed that the inner core (deepest part of Earth) is made of solid iron. However the inner core is surrounded by an outer core of iron and nickel that is believed to be molten material.
Every metal has it's own melting point where that metal is converted from solid to liquid...so as the temperature decreases the molecules in the metal loses energy and collides more slowly...and starting to collide within a fixed area...therefore the metal slowly converts to solid.
