On heating, the solid to a temperature T, let its volume becomes V, then, Change in the volume of a solid ΔV = V – V°, Like linear expansion, the change in volume ΔV is found to be proportional to its original volume V°, and the change in temperature ΔT. 1. WATER. They push one another farther away as the amplitude of vibrations increases. Thermal Expansion and Contraction. Length of metal bar getting longer on heating. Thermal expansion describes the tendency of an object to change its dimension either in length, area or volume due to heat. When there is a sudden change in temperature (increase) most of the elements expand. Have you ever taken a still-hot drinking glass right out of the dishwasher, poured an ice-cold beverage into it and witnessed the glass suddenly crack? Below 4 °C, the volume increases, and therefore the density decreases [Fig. Therefore, the coefficient of volume expansion of liquids is greater than the solids. Cracks in the road when the road expand on heating. If the temperature increases, then the volume of the material also increases. One design is the capacitance dilatometers. Let its length on heating to a temperature T  becomes L. Thus, Increases in length of the rod = ΔL = L – L0, It is found that change in length ΔL of the solid is directly proportional to its original length L°, and the change in temperature Δ T. That is, Where α is called the coefficient of linear thermal expansion of the substance. When air is heated, it expands and becomes less dense than the surrounding air, which then exerts an (upward) force on the hot air and makes steam and smoke rise, hot air balloons float, and so forth. To join steel plates tightly together, red hot rivets are forced through holes in the plates. This to avoid the cables becoming too tight and breaking in cold weather when the cable material contracts. Windows of metal framed need rubber spacers to avoid thermal expansion. A bimetal strip consists of two thin strips of different metals such as brass and iron joined together. Metal framed windows need rubber spacers 3. The … Thermal Expansion of water : Water exhibits an anomalous behavour; it contracts on heating between 0 °C and 4 °C. VOLUME GAS THERMOMETERS.
