The Bar and Gauze Apparatus is used for demonstrating the expansion of solids due to heating and contraction caused by cooling. Here are some details about this apparatus:
Description: The apparatus consists of an aluminum metal bar mounted on a rod with an insulated handle. Additionally, there is a U-shaped metal gauge also mounted on an insulated handle.
Function: When heated, the metal bar expands, and when cooled, it contracts. The U-shaped gauge allows learners to observe this expansion and contraction. The gauge fits closely around the bar either lengthwise or through holes, and the difference in length becomes noticeable after heating.
Ideal Use: This quality product from JAPSON is ideal for school laboratories in developing countries across Asia, Africa, and South America.
