Question

define avogadro law

Answer 1

Hey friend,

Your answer is Here,

〰〰〰〰〰〰〰〰〰〰
Avogadro's Law--:

equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.

At given mass the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

It Saw

$v \infty n \\ \\ so \: \\ \frac{v}{n} = k$

And

When we compare two different sets on same condition,

It saw

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

Thanks

Answer 2

◇ Avogadro's law is the relation which states that at the same temperature and pressure, equal volumes of all gases contain the same number of molecules. The law was described by Italian chemist and physicist Amedeo Avogadro in 1811.

Avogadro's Law Equation

There are a few ways to write this gas law, which is a mathematical relation. It may be stated:

k = V/n

where k is a proportionality constant V is the volume of a gas, and n is the number of moles of a gas

Avogadro's law also means the ideal gas constant is the same value for all gases, so:

constant = p1V1/T1n1 = P2V2/T2n2

V1/n1 = V2/n2

V1/n2 = V2/n1

where p is pressure of a gas, V is volume, T is temperature, and n is number of moles

Implications of Avogadro's Law

There are a few important consequences of the law being true.

◇ The molar volume of all ideal gases at 0°C and 1 atm pressure is 22.4 liters.

◇ If pressure and temperature of a gas are constant, when the amount of gas increases, the volume increases.

◇ If pressure and temperature of a gas are constant, when the amount of gas decreases, the volume decreases.

◇ You prove Avogadro's Law every time you blow up a balloon.
