Boyles Law Exhibit

Background

This project demonstrates "Boyle's Law" of Physics which states:
Boyle's law states that when the temperature of a given mass of confined gas is constant, the product of its pressure and volume is also constant. When comparing the same substance under two different sets of conditions, the law can be expressed as:

P₁ x V₁ = P₂ x V₂

showing that as volume increases, the pressure of a gas decreases proportionally, and vice versa.

In this exhibit a rotary handle allows visitor to change the volume within a Glass Cylinder, which in turn increases the pressure inside the container. A digital pressure gauge displays the variation in pressure in real time as the piston is turned.

Boyle's law, is an experiment that describes how the pressure tends to decrease as the volume of the container increases. Boyle's law is often used as part of an explanation on how the breathing system works in the human body. This commonly involves explaining how the lung volume may be increased or decreased and thereby cause a relatively lower or higher air pressure within them. This forms a pressure difference between the air inside the lungs and the environmental air pressure, which in turn precipitates either inhalation or exhalation as air moves from high to low pressure.

This project was developed for an NGO which is into building Scientific Exhibitions, Museums and upgrade Science Demonstration infrastructure in schools called Deenabandhu. As part of an Fun Science Gallery they were setting up this exhibit was developed by Ideas Unlimited, Mysuru.

Deenabandhu is a charitable Non-Profit Organization located in Chamarajnagar. Deenabandhu works towards the education and rehabilitation of orphan, destitute and estranged children. The trust is also into Science, innovation and teaching Science to school children and other activities.
