Thermal expansion is the increase, or decrease, of the size (length, area, or volume) of a body due to a change in temperature. Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids. Linear thermal expansion is. Thermal expansion generally decreases with increasing bond energy, which also has an effect on the melting point of solids, so, high melting point materials are more likely to have lower thermal expansion. In general, liquids expand slightly more than solids. The thermal expansion of glasses is higher compared to that of crystals. Thermal Expansion of Liquids Apparatus flask containing liquid with high coefficient of thermal expansion – such as ethanol with a bit of food colouring- with cork stopper fitted with a glass tube Action The students cup their hands around the flask and observe the rise of the liquid in the tube.

Thermal expansion of liquids pdf

Thermal Expansion of Liquids Apparatus flask containing liquid with high coefficient of thermal expansion – such as ethanol with a bit of food colouring- with cork stopper fitted with a glass tube Action The students cup their hands around the flask and observe the rise of the liquid in the tube. The coefficient of thermal expansion is also often defined as the fractional increase in length per unit rise in temperature. The exact definition varies, depending on whether it is specified at a precise temperature (true coefficient of thermal expansion or α− or over a temperature range . Thermal expansion is the increase, or decrease, of the size (length, area, or volume) of a body due to a change in temperature.
