What was the result of Boyle's experiment?
Robert Boyle, a chemist and physicist from the 17th century, discovered that the volume of gas, meaning how much space it occupies, is related to its pressure—and vice versa. He found that if you pressurize a gas, its volume contracts. If you decrease its pressure, its volume increases.
What does Boyle's law explain?
What is Boyle's law? Boyle's law is a gas law given by the Anglo-Irish chemist Robert Boyle in 1662. He stated that the pressure exerted by a gas is inversely proportional to the volume occupied by it at a constant mass and temperature.
What is the conclusion of Boyle law experiment?
Conclusion: Robert Boyle, through experimentation, found the inverse relationship between gas pressure and gas volume for a given amount of gas at a constant temperature and atmospheric pressure. Looking at the raw data from Boyle's classical experiment, the data expresses the clear cut relationship.

What does Boyle's law teach?
Summary of Boyle's law. Boyle's law explains that pressure and volume are always inversely proportional at a given temperature of a gas. It explains that when the volume of the lung increases during inspiration, the pressure in the lung will decrease.
What is Boyle's law KIDS definition?
Robert Boyle, a famous English chemist, discovered in 1662 that if you pushed on a gas, its volume would decrease proportionately. For example, if you doubled the pressure on a gas (increase the pressure two times), its volume would decrease by half (decrease the volume two times).
What is a good example of Boyle's law?
Breathing During respiration, our lungs make use of Boyle's law. While inhaling, the lungs are filled with air; therefore, they expand. The volume increases, hence the pressure level goes down. Similarly, when the lungs are evacuated of air, they shrink; therefore, the volume reduces and the pressure increases.
What is Robert Boyle's law?
Robert Boyle is best known in chemistry classrooms for Boyle’s law, which describes the fundamental relationship between the pressure of a gas and the volume it occupies. But Boyle’s law was never stated outright in Boyle’s work.
Who engraved Robert Boyle?
Engraving of Robert Boyle by George Vertue, ca. 1740.
Who discovered the inverse relationship between pressure and volume?
In 1676 a French priest, Edme Mariotte, independently published results showing the inverse relationship between pressure and volume. Mariotte went a step further than Boyle in stating that this relationship was valid only for a constant temperature. For these discoveries Boyle’s law is known as Mariotte’s law in France.
What is the result of Boyle's law?
This is accompanied by an increase in the pressure exerted by the air on the balloon, as a consequence of Boyle’s law. As the balloon is squeezed further, the increasing pressure eventually pops it.
Who invented Boyle's law?
Boyle’s law was put forward by the Anglo-Irish chemist Robert Boyle in the year 1662. For a gas, the relationship between volume and pressure (at constant mass and temperature) can be expressed mathematically as follows. Where P is the pressure exerted by the gas and V is the volume occupied by it.
What is the product of the initial pressure and the initial volume of a gas?
In other words, the product of the initial pressure and the initial volume of a gas is equal to the product of its final pressure and final volume (at constant temperature and number of moles). ...
Why is Boyle's law important?
Boyle’s law is significant because it explains how gases behave. It proves beyond a shadow of a doubt that gas pressure and volume are inversely proportional. When you apply pressure on a gas, the volume shrinks and the pressure rises.
What is the law of balloons?
A balloon is a good example of Boyle’s law in action. The balloon is inflated by blowing air into it; the pressure of the air pulls on the rubber, causing the balloon to expand. When one end of the balloon is compressed, the pressure within rises, causing the un-squeezed section of the balloon to expand outward.
What is the law of gas?
Boyle’s law is a gas law which states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it . In other words, the pressure and volume of a gas are inversely proportional to each other as long as the temperature and the quantity of gas are kept constant.
Who discovered the relationship between volume and pressure?
The relationship was also discovered by the French physicist Edme Mariotte (1676). Boyle's law, showing the relationship between volume and pressure when mass and temperature are held constant. The law can be derived from the kinetic theory of gases assuming a perfect (ideal) gas ( see perfect gas ).
Who first described the elastic properties of gas?
The first is Boyle’s law, which refers to the elastic properties of the gas; it was described by the Anglo-Irish scientist Robert Boyle in 1662 in his famous “ . . . Experiments . . . Touching the Spring of the Air . . . .” It states…
Which law states that the pressure exerted by a given gas is proportional to its density?
Boyle’s law—that the pressure exerted by a given gas is proportional to its density if the temperature is kept constant as the gas is compressed or expanded—follows immediately from Bernoulli’s assumption that the mean speed of the molecules is determined by temperature alone. Departures from…
Do real gases obey Boyle's law?
Real gases obey Boyle’s law at sufficiently low pressures, although the product pv generally decreases slightly at higher pressures, where the gas begins to depart from ideal behaviour. Demonstration of Boyle's law showing that for a given mass, at constant temperature, the pressure times the volume is a constant.
What is Boyle's law?
Physical Chemistry. Boyle's law is a pressure versus volume relationship. The law was discovered by Robert Boyle in the 17th century. It states the pressure of a fixed amount of a gas is inversely proportional to its volume at a constant temperature. The law can be empirically proven.
How to do a gas experiment at home?
It can be performed at home. When the tip of a syringe is sealed with a cap, the air inside the syringe is isolated from the atmosphere. This will fix the amount of the gas. The weights (books) are added upon the plunger of the syringe. It will push the plunger downwards; in other words, the air in the syringe is compressed. By recording the weights of the books added and the volume reading from the syringe, we can establish the pressure-volume relationship.
What is the pressure on the air inside the syringe?
The pressure on the air inside the syringe is the pressure exerted by the weights plus atmospheric pressure.
Why is proper lubrication necessary?
The proper lubrication is necessary to eliminate friction. The end of the syringe should tightly fix by a sealed cap. Otherwise, the experiment will fail. The syringe must be properly fixed, so it can firmly withstand the weights.
How to reduce friction in a rubber gasket?
Procedure. Take the syringe and paste a thin layer of the lubricant to the rubber gasket of it with the help of a wood en split or tongue depressor. This will reduce friction. Pull the plunger of the syringe upwards—around 110 mL. Now, attach the seal cap to the syringe.
What did Boyle believe about chemical experiments?
Boyle believed that chemical experiments could demonstrate the truth of the corpuscularian philosophy. In this context he defined elements in Sceptical Chymist (1661) as “certain primitive and simple, or perfectly unmingled bodies; which not being made of any other bodies, or of one another, are the ingredients of which all those called perfectly mixt bodies are immediately compounded, and into which they are ultimately resolved.”
What did Boyle's theory of material change do?
Boyle’s theories of material change did nothing to eliminate the possibility of the transmutation of base metals to gold that was at the heart of alchemy . Indeed he practiced alchemy until the end of his life, believed that he had witnessed transmutation, and successfully lobbied Parliament to repeal England’s ban on transmutation.
What is the name of the atomist who argued for corpuscularism?
Boyle was an advocate of corpuscularism, a form of atomism that was slowly displacing Aristotelian and Paracelsian views of the world. Instead of defining physical reality and analyzing change in terms of Aristotelian substance and form and the classical four elements of earth, air, fire, and water—or the three Paracelsian elements of salt, sulfur, ...
What is the second edition of Boyle's law?
The second edition of this work, published in 1662, delineated the quantitative relationship that Boyle derived from experimental values, later known as Boyle’s law: that the volume of a gas varies inversely with pressure.
Who was the first person to discover that the volume of a gas decreases with increasing pressure?
Robert Boyle. 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. A leading scientist and intellectual of his day, he was a great proponent of the experimental method.
Who reengraved the image of the air pump?
Boyle at the age of 37, with his air pump in the background. François Diodati reengraved this image from an engraving by William Fairthorne, Opera varia (1680).
