what is a change of liquid to a solid?

Answer 1

I would use the term crystallization for most things. Solidification would work if the material does not form crystals.

Answer 2

The name of the change is freezing.

A substance freezes usually because it cools down, such as in the case of water, but what is happening is the molecules in the substance lose energy and therefore move less.

In a gas, such as Helium, the molecules have lots of energy to move around and move independently.

In a liquid, such as Water, the molecules have less energy and CAN move but they are always in contact with other molecules because they lack the energy to break apart.

In a solid, such as ice, the molecules have almost no energy and are therefore packed tightly together. the only movement the molecules in a gas make is to vibrate.

Answer 3

Freezing.

Answer 4

Freezing. Also an exothermic reaction.

solid to liquid is melting (endothermic)
liquid to gas is vaporization (endothermic)
solid to gas is sublimation (endothermic)
gas to solid is deposition (exothermic)

Answer 5

it is called freezing.

the molecules/atoms in a substance lose a degree of freedom due to the lack of temperature. and the substance becomes rigid.

Answer 6

freazing

Answer 7

freezing...

Answer 8

Freezing!! DUH! "doctor Z."
