Description :-
Simple, innovative kit allows you to perform a number of experiments on vacuum and air pressure. The kit clearly demonstrates the method by which a pump works. Also illustrates that air has mass and helps find its mass and density. Explain the effect of surrounding air pressure on a sealed balloon. The balloon will expand when the surrounding air is removed. And also demonstrate that liquid boils at reduced temperature when the surrounding air pressure is reduced with instructions.
