Gas is one of the most familiar phases of substances in human life. There are many physical and chemical laws that underlie how gases work, one of which is Boyle's law . Here is an explanation of Boyle's law!
Boyle's law discoverer
Boyle 's law is the law that underlies the physical properties of gases, namely pressure and volume. Boyle's law was proposed by an Irish philosopher, chemist, physicist, and writer named Robert Boyle in 1662.
However, Boyle's law is also often referred to as Mariotte's law. Reporting from Thought Co , Mariotte was a French physicist who also discovered Boyle's law independently in 1679.
Sounds like Boyle's law
Reporting from NASA's Glenn Research Center , Robert Boyle studied the relationship between the pressure (p) and volume (V) of a gas confined at a constant temperature.
Boyle found that the product of pressure and volume is nearly constant and is known as the ideal gas .
P x V = k
With,
- P: gas pressure
- V: volume gas
- k: constant gas ideal
The particles that make up the gas move freely. The collisions between the particles exert pressure. Meanwhile, temperature affects the kinetic energy of the particles. The higher the temperature, the higher the kinetic energy, resulting in the greater the pressure generated.
What does Boyle's law say ? Reporting from Chemistry LibreTexts , Boyle's law states that in an enclosed space, the volume of a given mass of gas changes inversely with pressure when the temperature is constant.
Boyle's law equation
Boyle's law is used to compare the state of a gas when its pressure and volume change at constant temperature. Boyle's law equation is written as:
With,
- P1: gas pressure at first state (N/m², Pa, or atm)
- P2: gas pressure in the second state (N/m², Pa, or atm)
- V1: volume of gas at first condition (m³)
- V2: volume of gas in the second state (m³)
The Boyle's law equation above compares the two gas states. At constant temperature, reducing the volume will increase the pressure of the gas. Meanwhile, increasing the volume will reduce the gas pressure.
