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 liquids like water. It discusses the relationship between the coefficient of linear expansion and the coefficient of volume expansion. It also provides an equation to find the expansion of area due to a change in temperature and not just length and volume. This video contains plenty of examples, formulas / equations, and practice problems.

@ramich.x 4 жыл бұрын

In the "area" question you calculated the differences of lenght and width separately and multiplied the new lenght and width to get the expanded area, and in the volume question you calculated only the difference in the volume. Which way is correct? It does not give out the same answer unless you multiply the ◇V by 3 for volume (or multiply by 2 for area)

When calculating change in area and change in volume we were taught to multiply the Coefficient values by 2 for area and 3 for volume....is this accurate?

@thecherrythatkakyoinverbal8931 5 жыл бұрын

Yes, it's gamma(volume) = 3(alpha) and in case of water, the coefficient is always 3alpha because length and breadth of water can even be the room in which it's put. Thus, it's gamma (which is equal to three times alpha)
