Question

which formula is used for Boyle's Law and Avagdro's law???


​

Answer 1

✨ Boyle's law ✨

at constant temperature the pressure of a fixed amount of gas varies inversely with its volume.

p inversely proportional to V.

then ,

P1 V1= P2 V2 = constant.

then,

$\frac{p1}{p2} = \frac{v2}{v1}$

✨ Avogadro law ✨

it state that equal volume of all gases under the same condition temperature and pressure certain equal number of molecules.

then ,

V directly proportional to N

then,

$\frac{v1}{v2} = \frac{n1}{n2}$

Answer 2

Explanation:

Boyle’s law states the relation between volume and pressure at constant temperature and mass. Robert Boyle conducted an experiment on gases to study the deviation of its behaviour in changed physical conditions.

It states that under a constant temperature when the pressure on a gas increases its volume decreases. In other words according to Boyle’s law volume is inversely proportional to pressure when the temperature and the number of molecules are constant.

p ∝ 1/V

p ∝ 1/Vp = k1 1/V. ( K is Constant )

† Avogadro’s law (Avogadro’s hypothesis or Avogadro’s principle)

Avogadro’s law states that under conditions of constant pressure and temperature, there is a direct relationship between the number of moles and volume of a gas. This was Avogadro’s initial hypothesis. This law was applicable to ideal gases, while real gases show a slight deviation from it.

The modern definition of Avogadro’s law is that for a particular mass of an ideal gas, the amount (number of moles) and volume of the gas are directly proportional, provided the temperature and pressure conditions are constant.

Avogadro’s law’s mathematical formula can be written as:

V ∝ n or V/n = k

Where “V” is the volume of the gas, “n” is the amount of the gas (number of moles of the gas) and “k” is a constant for a given pressure and temperature.
