The difference between solids, liquids, and gases at a molecular level is how much room the atoms have to move around. In solids, the atoms are packed closely together not leaving much room to move around, thus giving it a definite shape and volume. The atoms in liquids have a little more room to move around and can take the shape of its container but still have a definite volume.
water is a liquid but wood isn't its a solid :D
ones solid and ones liquid
There is no actual name for a solid and liquid. An item can be a solid and liquid, but that is only under different pressures. For instance: The iron that makes up the Earths core is a solid, but that same material that is found in the Earths upper mantel is a liquid. This is because of the pressure differences
An actual single molecule is no different in a gaseous, liquid or solid state. However the thermal (kinetic) energy present in it varies between the states.
liquid
Ice is a solid, water is a liquid, and oxygen is a gas in the air we breath.
The inner core is a solid, and the outer core is a liquid.
solid liquid
Liquid.
One method is filtration, where the mixture is poured through a filter paper that traps the solid particles while allowing the liquid to pass through. Another method is centrifugation, which uses centrifugal force to separate the solid from the liquid based on differences in density.
Solid
Changing the liquid state to solid state is known as freezing, changing from solid state to liquid state is known as melting and changing from liquid or solid state to gaseous state is known as evaporation.
