Boyle's law, the principle that the pressure on a gas is inversely proportional to its volume at constant temperatures, is demonstrable with everything from balloons to soda cans to SCUBA gear. Aerosol cans and syringes both rely on Boyle's law in order to perform their functions as well.Know More
In an aerosol can, the contents are mixed with a gas under pressure high enough to render the gas into a liquid. When the nozzle is opened, however, this reduces the pressure suddenly, allowing the gas to expand. As it does so, it forces its way out of the nozzle, carrying the contents with it. The same effect occurs when a pressurized soda can is opened, allowing pressurized carbon dioxide to form bubbles in the beverage.
Drawing blood with a syringe uses Boyle's law in a different way. When the plunger of the syringe is pulled back, it increases the volume of the chamber inside the syringe. This reduces the pressure, creating a vacuum effect. This draws blood into the chamber through the needle.
Divers must keep Boyle's law in mind at all times. When a diver descends, the pressure around him increases. This forces nitrogen into solution inside his bloodstream. If he ascends too rapidly, the dissolved nitrogen expands suddenly, forming bubbles. This causes the painful and potentially life-threatening condition known as the bends, and only returning to a pressurized environment can reverse it.Learn more about States of Matter
An example of Gay-Lussac's Law in everyday life is the shooting of a gun. As gunpowder burns, it creates superheated gas, which forces the bullet out of the gun barrel following Gay-Lussac's Law. Other everyday life examples can be found in things that use gas and pressure in order to function.Full Answer >
In a given container, billions of particles of gas are constantly moving around randomly, colliding with the sides of the container. With thousands of collisions per second, individual collisions do not register, but an average that amounts to a constant force known as the pressure of gas.Full Answer >
According the kinetic molecular theory, gas in a closed container exerts pressure on the walls of that container because its molecules are in constant motion, which causes some molecules to impact the walls. The more the gas molecules impact the walls of the container, the greater the pressure.Full Answer >
In real life, there are many different applications of geometry including everyday uses such as the "stop sign," which is an octagon shape. The shape, volume, location, surface area and various other physical properties are central to the objects around people.Full Answer >
