Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions?

Charles's Law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions

There are several gas equations in various processes:

PV = nRT

PV = NkT

N = number of gas particles

n = number of moles

R = gas constant (8,31.10 ^ 3 J / kmole K

k = Boltzmann constant (1,38.10 ^ -23)

n = = N / No

n = m / M

n = mole

No = Avogadro number (6.02.10 ^ 23)

m = mass

M = relative molecular mass

In the same temperature and pressure, in the same volume conditions, the gas contains the same number of molecules

So it applies: the ratio of gas volume will be equal to the ratio of gas moles

V1: V2 = n1: n2

2. Boyle's Law

At a fixed temperature, the gas volume is inversely proportional to the pressure applied

p1.V1 = p2.V2

When the gas pressure is kept constant, the gas volume is proportional to the temperature

V1 / T1 = V2 / T2

When the gas is heated in a tube whose volume does not change, the gas pressure in the tube is proportional to its absolute temperature

P1 / T1 = P2 / T2

Combined with Boyle's law and Gay Lussac's law

P1.V1 / T1 = P2.V2 / T2

P1 = initial gas pressure (N / m2 or Pa)

V1 = initial gas volume (m3)

P2 = gas end pressure

V2 = the final volume of gas

T1 = initial gas temperature (K)

T2 = gas end temperature

So the correct answer is Charles' Law, where at constant pressure, the volume of gas will be inversely proportional to its temperature

states that volume occupied by a fixed quantity of a gas is directly proportional to the absolute temperature (Kelvin) at constant pressure.

Further Explanation:

Charles’s law:

Charles’s work showed that at constant pressure, the volume-temperature relationship for a fixed amount of gas is linear. In other words, Charles’s law can be stated that at constant pressure, the volume occupied by a fixed amount of a gas is directly proportional to its absolute temperature (Kelvin). This relationship is known as Charles’s law.

The mathematical representation of Charles’s law is,

                  [P and n are constant]

Where,

The relationship can also be expressed as,

                                   [P and n are constant]

Or,

                     [P and n are constant]

Results of Charles’s law are as follows:
