http://www.mocomi.com presents: Boyle's balloon test? REQUIREMENTS A 50ml syringe A small sized baloon Thread WHAT TO DO First trap a small amount of air in the baloon and tie a knot. Place the bulb in the syringe WHAT HAPPENS When we place the bulb inside the syringe without squeezing the piston the ball remains in its same same due to the normal atmospheric pressure. The moment we close the outlet of the syringe and squeeze the piston the bulb becomes smaller under increased pressure. WHY THIS HAPPENS The baloon remains the same size when the pressure decreases and the volume increases. But when pressure increases the volume decreases therefore making the baloon compress to a smaller size. Boyle's law describes the inversely proportional relationship between the absolute pressure and volume of a gas.
