Solid
Solids are defined by the following characteristics:
Definite shape (rigid)
Definite volume
Particles vibrate around fixed axes
If we were to cool liquid mercury to its freezing point of −39oC
, and under the right pressure conditions, we would notice all of the liquid particles would go into the solid state. Mercury can be solidified when its temperature is brought to its freezing point. However, when returned to room temperature conditions, mercury does not exist in solid state for long, and returns back to its more common liquid form.
Liquid
Liquids have the following characteristics:
No definite shape (takes the shape of its container)
Has definite volume
Particles are free to move over each other, but are still attracted to each other
A familiar liquid is mercury metal. Mercury is an anomaly. It is the only metal we know of that is liquid at room temperature. Mercury also has an ability to stick to itself (surface tension) - a property all liquids exhibit. Mercury has a relatively high surface tension, which makes it very unique. Here you see mercury in its common liquid form.
Mercury.
If we heat liquid mercury to its boiling point of 357oC
, and under the right pressure conditions, we would notice all particles in the liquid state go into the gas state.
Gas
Gases have the following characteristics:
No definite shape (takes the shape of its container)
No definite volume
Particles move in random motion with little or no attraction to each other
Highly compressible
