It depends on the metal but often it will change phase and crystal form and have different properties. As an example steel when molten is in what is called the austenitic phase. This is a face Centered Cubic crystal structure. When quickly quenched it becomes martensitic which is brittle and Body Centered Tetragonal. Cooling down slowly will produce a pearlite structure.
If a liquid metal is poured into a mold it will take the shape of that mold and when cooled will keep the shape of that very mold. It will also contract/shrink.
When a metal or any other solid, liquid, or gas is heated they expand. This happens because the molecules that make these substances start to move or "shake" more than they already do. If they are heated to a certain point (depending on the substance) they will shake enough to break free. if you had a solid it will melt into a liquid, and a liquid into a gas.
Metal that is heated will expand(meaning to become larger), and metal contracts(shrinks) when it is cooled. I think that it is because when it is heated, the molecules spread apart(sort of like when you heat water), and the opposite happens when it is cooled.
Metal will normally change in several physical ways when cooled:
It contracts.
contract
big boo
they tend to vibrate
No. A chemical change occurs only when a new substance is produced with new and different properties. In your example, a physical change occurred because only the metal's physical properties were affected. Nothing new was created.
It heats up
A solid can change Into a liquid when it is heated Example- when heated solid chocolate, the chocolate changes into a liquid. A liquid Can change into a solid when it is cooled Example - If you leave juice in the freezer , the liquid changes into a solid.
When matter is heated it will expand
It contracts.
It contracts.
it will not attract
It changes the vibrations of the molecules.
When molecules are heated they become more active. When they are cooled, the slow down.
ummm it will definetely expand....if the materials you"re talking about is the term for science.
they tend to vibrate
When heated it get larger and when you freeze it the matter gets smaller with an exeption to ice
if they are heated then they turn to a liquid, if that are a soled well they are hard like ice
The flesh will bring out goose pemples
convection means when something is heated it expands or conducts eg. metal is heated it contracts when it is cooled it contracts.
goes bigger
