practical application of boyles law

Dear student!
According to Boyle's law: the pressure exerted by a gas held at constant temperature is inversely proportional to the volume of the gas. So, at constant temperature P V =Constant.

Hence, the best example of Boyle's law is "Syringe" as when we draw a fluid inside a syringe , the volume inside is increased making the pressure outside greater which forces the fluid into the syringe.

And hence, over all product of pressure and volume becomes constant. i.e. PV =constant for a syringe.

One practical application of Boyle's law would be the action of a syringe. When you draw a fluid into a syringe, the volume inside is increased, the pressure inside decreases, making the pressure outside greater, which forces the fluid into the syringe. Boyle's law states that at a constant temperature, the product of the pressure and the volume is a constant.

 A practical application illustrating Boyles Law would be the action of a syringe. When we draw fluids into a syringe, we increase the volume inside the syringe, this correspondingly decreases the pressure on the inside where the pressure on the outside of the syringe is greater and forces fluid into the syringe. If we reverse the actin and push the plunger in on the syringe we are decreasing the volume on the inside which will increase the pressure inside making the pressure greater than on the outside and fluids are forced out.

A more life dependent example of Boyles Law is the ction of the diaphragm of our body. This is a muscle that is located just below the lungs. When we inhale the diaphragm moves downward allowing the lungs an increased volume. This decreases the pressure inside the lungs so that the pressure is less than the outer pressure. This results in forcing air into the lungs. When we exhale the diaphragm moves upward and decreases the volume of the lungs. This increases the pressure inside the lungs above the pressure on the outside of the lungs so that gases are forced out of the lungs. Of course, all of this is totally automatic and we take this important cycle which is performed hundreds of times a day for granted until we receive a sharp blow to that region that briefly paralyzes the diaphragm muscle. We say the wind was knocked out of us, but Boyles Law was not allowed to function.
