Heat convection in liquids and gases

Principle

When fluids or gases are heated, convection occurs. The warmed medium rises due to its smaller density. A circulation tube is filled with water and heated on one side. A drop of food color makes the stream visible. Heat convection in air is demonstrated with a spiral over a flame.

Benefits

• Optimised for demonstration experiments: Transformation from horizontal into vertical direction
• Secure fastening of burners and hot vessels
• Glass equipment, liquid levels and flowing liquids can be observed easily on the plain background
