Liquid Expansion Formula Softschools

Answer: The expansion is given by the equation: ΔL = L α ΔT. substituting the value of L, the change in temperature and α, ΔL = (0.01 m)* (180*10 (-6) /°C)*10°C = 18*10 (-6) m. ΔL = 18*10 (-8) cm. 2) A liquid is subject to a change of temperature of 50 °C, it changes its length occupied from 10 cm to 9 cm, what is the coefficient of expansion of the liquid?

Thermal Expansion of Solids and Liquids Physics

Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids. Linear thermal expansion is ΔL = αLΔT, where ΔL is the change in length L, ΔT is the change in temperature, and α is the coefficient of linear expansion, which

How to calculate thermal expansion x-engineer

Thermal expansion causes variations in volume for solids and liquids function of temperature. Knowing the initial volume V 0 [m 3] of a given solid, the temperature difference ΔT [ºC] and the coefficient of linear expansion of the solid α [1/ºC], the change in volume ΔV [m 3] of the solid can be calculated as:
