Heat Equipments
Ball & Ring
Description :-This brass ball and ring demonstrates thermal expansion of the metals. The ball passes through the ring freely when both are at same temperature whereas the ball will not pass through the ring when heated. Comprises of a 25mm dia brass ball and a brass ring both attached to separate wooden handles.

Liquid Convection Apparatus
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.
