Solid Metals Undergo Greater Thermal Expansion Than Liquids Do. This physics video tutorial explains the concept of thermal expansion such as the linear expansion of solids such as metals and the volume contraction of liq. What is the underlying cause of thermal expansion. Thermal expansion joints like these in the Auckland Harbour Bridge in New Zealand allow bridges to change length without buckling. Solids also undergo thermal expansion.
Measuring the linear expansion of solids as a function of temperature. Liquids cannot be compressed. Thermal expansion of some common metals. Thermal anomaly of water. What are the basic properties of thermal expansion. In a thermometer for example the expansion of alcohol is much greater than the expansion of the glass containing it.
At 0 C αv 37 10-3 K 1 which is much larger than that for solids and liquids.
Railroad tracks and bridges for example have expansion joints to allow them to freely expand and contract with temperature changes. What is the underlying cause of thermal expansion. Thermal expansion of solids liquids and gases. First thermal expansion is clearly related to temperature change. Solid metals undergo greater thermal expansion than liquids do. Second it depends on the.
