Explain how the variables of volume, temperature, and pressure interact when we are examining gas laws

The gas laws are:

Charles's law: V1 / T1 = V2 / T2 Gay - Lussac's law: P1 / T1 = P2 / T2 Boyle's law: P1 * V1 = P2 * V2 The general gas law: (P1 * V1) / T1 = (P2 * V2) / T2

Explanation:

Gas laws were designed in the seventeenth century when scientists of the century realized the relationships between the pressure, volume, and temperature of a gas in a closed system.

In Charles's law, the variables are directly proportional. In Gay-Lussac's law, the variables are directly proportional. In Boyle's law, the variables are inversely proportional. In the general gas law, the variables are directly proportional.

Variables are inversely proportional to the product.

In other words, if one variable increases, the product another decreases.

And if the variable decreases the product increases.

Variables are directly proportional to the product.

In other words, if the variable applied to the gas increases, the product also increases. This means that if the variable changes for more or less, your product will too.

The major know gas laws are

1. Boyle's law

2. Charles law

3. Pressure law

And

4. Ideal gas equation.

Boyle's law states that the pressure P of a given mass of gas is inversely proportional to its volume V assuming temperature remains constant. From this law, increase in pressure will lead to decrease in volume and likewise vice versa.

Mathematically,

P = kV

K = P1V1 = P2V2 = P3V3 ... PnVn

Charles law states that the volume V of a given mass of gas is directly proportional to its temperature T provided the pressure remains constant.

What this gas law is trying to say is that increase in volume will lead to increase in temperature as long as pressure remains constant.

Mathematically,

V = kT

k = V1 / T1 = V2 / T2 = V3 / T3 ... Vn / Tn

Pressure law states that the Pressure P of a fixed mass of gas is directly proportional to its absolute temperature T provided that it volume remains constant.

What this law is trying to say is that, increase in pressure will lead to increase in temperature of the gas as long as the volume remains constant.

P = kT

K = P1 / T1 = P2 / T2 = P3 / T3 ... Pn / Tn ...

The combined gas equation therefore combined the above three gas laws to give "ideal gas" equation.

From ideal gas equation,

PV = nRT

Where p = pressure of the gas

V = volume of the gas

R = ideal gas constant

T = temperature of the gas

n = number of moles of the gas present.

R = PV / nT.

This equation was used to derive the ideal gas constant by combing the above three equations (Boyle's law, Charles law and pressure law).
