I'm Robert Boyle, a chemist and physicist. I'm the one who discovered that when pressure increases, a gas's volume decreases and vice versa—the famous Boyle's law.
What is Bolye's law?At constant temperature, Boyle's law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume.
I have shown that the volume of air trapped by a liquid in the closed short side of a J -shaped tube is reduced in exact proportion to the pressure produced by the liquid in the long side of the tube.
I stated that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; that is, in the form of an equation, pv = k, a constant.
The real life application of Boyle’s Law is when you fill an air to your bike tire. When you pumped air into a tire, the gas molecules inside the tire are compressed and packed together. This increases the gas pressure, and it will starts pushing against the tire's walls.
