what are the applications of boyle's law?

Question

about chemistry

Answer 1

Applications huh? Here's a practical aircraft application.

Well I worked on aircrafts before and our shock struts ( like shock absorbers) are filled with nitrogen. Depending on the weight of the aircraft the volume may decrease or increase (therefore rising or lowering the aircraft) So we can ensure that we have enough nitro in there we have a gauge that tells us the pressure. We compare that pressure to the height of the strut (which gives us the volume) and check our chart (which utilizes boyles law) to ensure or pressure is appropriate for the volume.

Answer 2

Boyle's law (sometimes known as the Boyle Mariotte law) is one of the gas laws. Boyle's Law is named after the Irish natural philosopher Robert Boyle (Lismore, County Waterford,1627-1691) who was the first to publish it in 1662. The relationship was brought to the attention of Boyle by two friends and amateur scientists, Richard Towneley and Henry Power, who discovered it. Boyle confirmed their discovery through experiments and published the results. According to Robert Gunther and other authorities Boyle's assistant Robert Hooke, who built the experimental apparatus, may well have helped to quantify the law; Hooke was accounted a more able mathematician than Boyle. Hooke also developed the improved vacuum pumps necessary for the experiments. The French physicist Edme Mariotte (1620-1684) discovered the same law independently of Boyle in 1676, so this law may be referred to as Mariotte's or the Mariotte Boyle law.

Boyle's Law states that the product of the volume and pressure of a fixed quantity of an ideal gas is constant, given constant temperature. Expressed mathematically, the formula for Boyle's law is:

V is volume of the gas.
p is the pressure of the gas.
k is a constant (see Note 1).
The value of k is computed from measurements of volume and pressure for a fixed quantity of gas. After making a change to the system, typically by forcing a change in the volume of the vessel containing the fixed quantity of gas, the new volume and new pressure are measured. The result of computing the product of the measured new volume and the new pressure should be the original value of the constant k. Without being too rigorous at this point, the equation says that, after forcing the volume V of the fixed quantity of gas to increase, keeping the gas at the initially measured temperature, the pressure P must decrease proportionally. Conversely, reducing the volume of the gas increases the pressure.

Answer 3

Boyle's law states that at a given temperature the product of pressure x volume is a constant at a given temperature
Its expression is pV = n RT

P pressure V volume T absolute temperature T = t (Celsius) +273

n number of moles of the gaz R is a constant

It is used in problems of that type


The volume of a gas is 25 l at 0°C . Calculate the pressure knowing that you have 20 g Of oxygen

Answer 4

according to boyle's law 'at fixed temperature the volume of a given amount of dry gas is directly propotional to the pressure'.thus boyle's law is used in calculating the volume of a gas when the pressure is known.the exp is as follows:
p1/v1=p2/v2

Answer 5

pV=k

V is volume of the gas.
p is the pressure of the gas.
k is a constant
