The least compressible state of matter is a solid. But even solids may be compressed slightly.
A Neutron Star consists of matter so compressed that it is now composed only of neutrons.
And of course, in a Black Hole, things are more compressed again.
But both neutron Star and Black Hole are degenerate matter - they are no longer considered ordinary matter.
Of course, the solid state of matter. And the most compressible is the gas phase (in the classical physics).
solids are least compressible.
Solids.
metal
gas
The solid state has the least molecular motion.
Solids, liquids and gases expand when heated, liquids and gases expand much more that solids. Gases can be compressed
The one with the least heat, therefore, solids.
Oil will sink in water, so is the least dense.
No. A material is heated, i.e. changes state, then hardens again. No chemical change, but at least a partial state change.
solid
When any state of matter is heated it expands.
metal is a solid that expands when heated also of course when liquids are heated and change state into a gas they expand but metal is cool because it expands before it changes state
When matter is heated the particles in the matter gain energy and begin to move or vibrate more depending on the state in which the matter is currently in. If the heat provided is significant enough they can change state too. Hope that was what you were looking for!
gas expand more than liquid and liquid expand more than solid.
I would have to say Gas.
This is the gas.
solid
No
Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts
This state of matter is the solid.
Molecules move faster when heated -- no matter what state they're in.
