Liquid Convection Apparatus

For demonstrating the phenomenon of thermal convection in liquids caused by temperature variation.

Description

For demonstrating the phenomenon of thermal convection in liquids caused by temperature variation.

Consists of a rectangular shaped borosilicate glass tube (w x h), 15 x 21cm with a funnel-shaped opening at the top for filling liquids. When this tube is partially filled with water and heated at one corner after adding a dye or potassium permanganate crystals or saw dust or aluminum powder, the movement of colors or particles illustrates the formation of convection currents.
