# State boyles law explain why it is an inverse relationship between the rate

### Relationships among Pressure, Temperature, Volume, and Amount - Chemistry LibreTexts Solids have molecules fixed in relation to each other. . Boyle's Law states that the product of the pressure and volume for a gas is a constant for a fixed amount . On Earth, matter exists in one of three states: solid, liquid or gas. Boyle's Law describes the relationship between pressure and volume at the volume of a given mass of gas is inversely proportional to pressure it is under. This is true even though the speed (temperature) of the individual molecules has not changed. The behaviour of a Gas can be studied by various laws known as the Gas laws. problems to inhale? Why is it so? Boyle's law states the relation between volume and pressure at constant temperature and mass. . Solution: B) We know that the rate of diffusion is inversely proportional to the square root of density. This is.

Ideal gas molecules do not attract or repel each other. The only interaction between ideal gas molecules would be an elastic collision with each other or with the walls of the container. Ideal gas molecules themselves take up no volume. While the gas takes up volume, the ideal gas molecules are considered point particles that have no volume. There are no gasses that are exactly ideal, but there are many that are close.

This is why the ideal gas law is extremely useful when used as an approximation for many situations.

### Gas laws - Wikipedia

The ideal gas law is obtained by combining Boyle's law, Charle's law, and Gay-Lussac's Law, three of the major gas laws. What Is Charle's Law? Charle's law, or the law of volumes, was discovered in by Jaques Charles and states that for a give mass of an ideal gas at constant pressure, the volume is directly proportional to it's absolute temperature. This means that as the temperature of a gas increases, so does its volume. What Is Gay-Lussac's Law? Gay Lussac's law, or the pressure law, was discovered by Joseph Louis Gay-Lussac in and states that, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.

This means that pressure indicates temperature. Portrait of Robert Boyle. When it comes to the effects of Boyle's law on the body, the gas law specifically applies to the lungs.

When a person breathes in, their lung volume increases and the pressure within decreases. Since air always moves from areas of high pressure to areas of low pressure, air is drawn into the lungs. The opposite happens when a person exhales. Since the lung volume decreases, the pressure within increases, forcing the air out of the lungs to the lower pressure air outside of the body. The breathing process, sometimes called respiration, can be simply broken down into two stages: Inhalation During inhalation, also called inspiration, the diaphragm contracts and pulls downward and the muscles between the ribs contract and pull upward, increasing the volume of the lung cavity and decreasing the pressure within.

As a result, air rushes in to fill the lungs. Boyle used non-SI units to measure the volume in. Hg rather than mmHg. Because PV is a constant, decreasing the pressure by a factor of two results in a twofold increase in volume and vice versa. The Relationship between Temperature and Volume: Charles's Law Hot air rises, which is why hot-air balloons ascend through the atmosphere and why warm air collects near the ceiling and cooler air collects at ground level.

Because of this behavior, heating registers are placed on or near the floor, and vents for air-conditioning are placed on or near the ceiling. The fundamental reason for this behavior is that gases expand when they are heated.

## Boyle's Law Examples in Real Life

Because the same amount of substance now occupies a greater volume, hot air is less dense than cold air. The substance with the lower density—in this case hot air—rises through the substance with the higher density, the cooler air.

A sample of gas cannot really have a volume of zero because any sample of matter must have some volume. Note from part a in Figure 6.

Similarly, as shown in part b in Figure 6. The Relationship between Volume and Temperature. The temperature scale is given in both degrees Celsius and kelvins. The significance of the invariant T intercept in plots of V versus T was recognized in by the British physicist William Thomson —later named Lord Kelvin. At constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature in kelvins. This relationship, illustrated in part b in Figure 6.

## Boyle's Law

The Relationship between Amount and Volume: InAvogadro postulated that, at the same temperature and pressure, equal volumes of gases contain the same number of gaseous particles Figure 6. Equal volumes of four different gases at the same temperature and pressure contain the same number of gaseous particles. Because the molar mass of each gas is different, the mass of each gas sample is different even though all contain 1 mol of gas.
