Liquid Convection Apparatus
Availability: Contact Us
For demonstrating the phenomenon of thermal convection in liquids caused by temperature variation. Consists of a rectangular shaped borosilicate glass tube, (w x h) 6"x 8-1/4" (150x 210mm), 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, potassium permanganate crystals, saw dust or aluminum powder, the movement of colors or particles illustrates the formation of convection currents.
Comes with a Teacher's Guide and reproducible Student Handout.
