Question

Which laws can be combined to form the ideal gas law?

Answer 1

Answer: Charles's law, Avogadro's law andd Boyle's law.

Charles law states the constant ratio of volume to temperature, at constant pressure. Boyle's law states the constat product of pressure and volumen at constant temperature. Avogadro's law states that equal volumes of gases at the same temperature and pressure have equal number of particles.

So, all those three laws combined state the relation of pressure, volume, temperature and number of particles of a gas, which is what the ideal gas law does: PV = n RT.

Answer 2

Charles’s law, Avogadro’s law and Boyle’s law can be combined to form the ideal gas law.

Further Explanation:

An idealgas is a hypothetical gas that is composed of a large number of randomly moving particles that are supposed to have perfectly elastic collisions among themselves.

Boyle’s law:

This gives inverse relationship between pressure and volume of gas. Mathematical form can be expressed as follows:

${\text{P}} \propto \dfrac{1}{{\text{V}}}$  

Or,

${\text{PV}} = {\text{k}}$                                                                            ...... (1)

Charles’s law:

This law provides direct relationship between volume and temperature of gas. Its mathematical expression is given below.

${\text{V}} \propto {\text{T}}$  

Or,

$\dfrac{{\text{V}}}{{\text{T}}} = {\text{k}}$                                                                              ...... (2)

Avogadro’s law:

This law states that volume of any gas is directly related to the number of moles of that gas, provided the temperature and pressure remain constant. Its mathematical form can be written as follows:

${\text{V}} \propto {\text{n}}$ …… (3)

Equation (1). (2) and (3) are combined to obtain following equation,

$\dfrac{{{\text{PV}}}}{{\text{T}}} = {\text{kn}}$                                                                              …… (4)

Here,

P is pressure of the gas.

V is volume of the gas.

T is absolute temperature of the gas.

n is number of moles of gas.

k is a constant value.

Equation (4) can be rearranged to form ideal gas expression as follows:

$\boxed{{\text{PV}} = {\text{nRT}}}$  

Where, R is universal gas constant.
