How did Boyle and Hooke make their discovery?
Using Hooke’s pump, Boyle and Hooke carried out experiments to investigate the properties of air and the vacuum, making their first great discovery: Boyle’s Law. They made their discovery using a glass tube similar to the one shown at the top of this page.
What is the history of Boyle’s law?
The History of Boyles Law. During the middle of the 1600’s Boyle made an important move to Oxford. He hired an assistant, an Englishman called Robert Hooke. With Hooke’s mechanical talents acting as a foil to Boyle’s own researches into air (the properties of gases), they produced the vacuum chamber or air-pump.
When did Boyle discover that air follows mathematical laws?
Boyle published this result in 1662. With its publication he emulated his hero Galileo for the first time. Galileo firmly believed that the world could be explained using mathematics – as indeed Pythagoras had in a much earlier age. Boyle had now shown by experiment that air follows mathematical laws.

How did Boyle discover his law?
Boyle discovered the relationship between pressure and volume in a gas that is now known as Boyle's law by using a vacuum chamber to change the pressure in a gas. He made careful observations and conducted a series of experiments to show that pressure and volume are inversely proportional to each other.
What was Boyle's discovery?
Known for his law of gases, Boyle was a 17th-century pioneer of modern chemistry. Every general-chemistry student learns of Robert Boyle (1627–1691) as the person who discovered that the volume of a gas decreases with increasing pressure and vice versa—the famous Boyle's law.
When did Boyle discover Boyle's Law?
One of their findings, published in 1662, later became known as “Boyle's law.” This law expresses the inverse relationship that exists between the pressure and volume of a gas, and it was determined by measuring the volume occupied by a constant quantity of air when compressed by differing weights of mercury.
Why was Boyle discovery important?
The apparatus had been designed by Hooke and using it Boyle had discovered a whole series of important facts. He had shown, among other things, that sound did not travel in a vacuum, he had proved that flame required air as did life, and he investigated the elastic properties of air.
How is Boyle's law used in real life?
You can observe a real-life application of Boyle's Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.
Who discovered that air is a mixture of gases?
In a series of experiments culminating in 1774, Priestley found that "air is not an elementary substance, but a composition," or mixture, of gases.
How does Boyle's law apparatus work?
A scale is fitted behind the glass tube so the volume of the air space can be measured proportionately. The reservoir contains water based colored fluid and, when the reservoir is pressurised by a small air pump, the fluid is forced up the glass tube and can be seen to compress the air inside the tube.

Statement of Boyle's law: For a fixed mass (number of moles 'n') of a gas at a constant temperature, the pressure (P) of the gas is inversely proportional to the volume (V) of the gas. At constant temperature, the pressure of a fixed amount (number of moles) of a gas varies inversely with its volume.

What was Boyle's atomic theory?
It is Boyle's Law for which he remains most famous. This states that if the volume of a gas is decreased, the pressure increases proportionally. Understanding that his results could be explained if all gases were made of tiny particles, Boyle tried to construct a universal 'corpuscular theory' of chemistry.

Demonstration of Boyle's law showing that for a given mass, at constant temperature, the pressure times the volume is a constant.
Who developed Boyle's law?
Daniel Bernoulli (in 1737–1738) derived Boyle's law by applying Newton's laws of motion at the molecular level. It remained ignored until around 1845, when John Waterston published a paper building the main precepts of kinetic theory; this was rejected by the Royal Society of England. Later works of James Prescott Joule, Rudolf Clausius and in particular Ludwig Boltzmann firmly established the kinetic theory of gases and brought attention to both the theories of Bernoulli and Waterston.
Who discovered the same law independently of Boyle?
The French physicist Edme Mariotte (1620–1684) discovered the same law independently of Boyle in 1679, but Boyle had already published it in 1662. Mariotte did, however, discover that air volume changes with temperature. Thus this law is sometimes referred to as Mariotte's law or the Boyle–Mariotte law.
What is the relationship between kinetic theory and ideal gases?
Boyle's law states that at constant temperature the volume of a given mass of a dry gas is inversely proportional to its pressure. Most gases behave like ideal gases at moderate pressures and temperatures.
How was the law of motion derived?
Boyle (and Mariotte) derived the law solely by experiment. The law can also be derived theoretically based on the presumed existence of atoms and molecules and assumptions about motion and perfectly elastic collisions (see kinetic theory of gases ). These assumptions were met with enormous resistance in the positivist scientific community at the time, however, as they were seen as purely theoretical constructs for which there was not the slightest observational evidence.

Why is Boyle’s law important?
Boyle’s Law is extremely helpful for SCUBA divers. As you dive deeper, the pressure increases on your body and decreases the volume in your lungs. As you ascend out of the depths of the ocean, you slowly release air from your lungs, which is compressed due to the pressure.
What is a real life example of Charles Law?
Real Life Example: A real life example of Charles’s law is leaving a basketball out in the cold weather. When a basketball if left in a cold garage or outside during the cold months, it loses its air inside (or volume). This is showing, with constant pressure, if the temperature drops, the volume decreases also.

Boyle discovered that pressure multiplied by volume is a constant. In other words, when you increase the pressure on a gas, the gas’s volume shrinks in a predictable way.

Human breathing system
Boyle's law is often used as part of an explanation on how the breathing system works in the human body. This commonly involves explaining how the lung volume may be increased or decreased and thereby cause a relatively lower or higher air pressure within them (in keeping with Boyle's law). This forms a pressure difference between the air inside the lungs and the environmental air pressure, which in turn precipitates either inhalation or exhalation as air move…
