What Is Boyle's Law and Equation?
In 1662, Robert Boyle discovered the volume and pressure of gasses are inversely proportionate when held at a constant temperature. Put simply, when volume rises, pressure drops, and vice versa.
The mathematic equation is equally as simple.
PV = k
In this equation, (P) represents pressure, (V) represents volume, and (k) is a constant.
This has become a basic principle in chemistry, now called "Boyle's law," and is included as a special case in the more general ideal gas law.
How Did Boyle Come up With His Law?
Using a vacuum pump invented by Otto von Guericke in 1654, Boyle carried out experiments investigating the properties of air and the vacuum.
During his experiments, he stumbled upon the greatest achievement of his life. By using a J-shaped glass tube that had air at the tip of the curve, Boyle altered the weight of the air using mercury and, as he did so, he saw that the space of air at the tip of the curve became smaller. He discovered that when you increase pressure on a gas, the gas's volume predictably shrinks.
Why Is Boyle's Law Important?
Boyle's law is important because it tells us about the behavior of gasses. It explains, with certainty, that the pressure and volume of gas are inversely proportional to one another. So, if you push on gas, its volume becomes smaller and the pressure becomes higher.
Examples of Boyle's Law in Life
You have probably been well-acquainted with Boyle's law for most of your life without realizing it. We experience examples of this law on a regular basis. The first example is a rather common one, assuming you have filled a tire with air before.
Generally, you fill a tire with somewhere between 30 to 35 PSI (pounds per square inch) of compressed air. This is a measurement of pressure. As you put more and more air into the tire, you are forcing all the gas molecules to get packed together, reducing their volume and increasing the pressure pushing on the walls of the tire. As long as the air temperature remains the same, you are experiencing a real life example of this law.

Answer:
Boyle's law, most often referred to as the Boyle–Mariotte law, or Mariotte's law (especially in France), is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases. A modern statement of Boyle's law is
Explanation:
The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.[1][2]
Mathematically, Boyle's law can be stated as
{\displaystyle P\propto {\frac {1}{V}}}P\propto {\frac {1}{V}} Pressure is inversely proportional to the volume.
or
{\displaystyle PV=k}PV=k Pressure multiplied by volume equals some constant {\displaystyle k}k.
where P is the pressure of the gas, V is the volume of the gas, and k is a constant.
The equation states that the product of pressure and volume is a constant for a given mass of confined gas and this holds as long as the temperature is constant. For comparing the same substance under two different sets of conditions, the law can be usefully expressed as
{\displaystyle P_{1}V_{1}=P_{2}V_{2}.}P_{1}V_{1}=P_{2}V_{2}.
This equation shows that, as volume increases, the pressure of the gas decreases in proportion.
