Thermal Expansion and Contraction - Study.com

WebThermal Expansion If the temperature increases, then the volume of the material also increases. Generally, this is known as thermal expansion. We can express it in this way that it is the fractional change in length or volume per unit change in temperature. In case of expansion of a solid, normally linear expansion coefficient is usually employed. WebVideo transcript. when you heat up liquids they expand so let's talk a little bit about thermal expansion in liquids in particular what we'll do in this video is we'll compare the properties of liquids with that of a solid from thermal expansion point of view now if we go back to solids we'll already defined a number called as alpha L the ... citizens bank boston massachusetts

WebThermal Expansion of Liquids The molecules of liquids are free to move in all directions within the liquid. On heating a liquid, the average amplitude of vibration of its molecules increases. The molecules push each other and need more space to occupy. The accounts for the expansion of the liquid when heated. WebThe amount of actual expansion is quite small since the coefficients of expansion are very small. If the 7 cm diameter lid were heated from 20°C to 60°C, the amount of expansion is only. ΔL = (7 cm) (13 x 10 -6 ) (40°C) = 0.0036 cm. Fortunately, even this small amount of expansion is sometimes sufficient to enable you to remove a stubborn lid.
