Linear Expansion
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
Area Expansion
Objects expand in all dimensions. That is, their areas and volumes, as well as their lengths, increase with temperature.
Volume Expansion
Substances expand or contract when their temperature changes, with expansion or contraction occurring in all directions.
Special Properties of Water
Objects will expand with increasing temperature, but water is the most important exception to the general rule.
