## What is Avogadro law class 11?

Avogadro Law. Avogadro Law. It states that equal volumes of all gases under the same conditions of temperature and pressure. contain equal number of molecules.

## What is Avogadro gas law formula?

The number of molecules or atoms in a specific volume of ideal gas is independent of size or the gas’ molar mass. Avogadro’s Law is stated mathematically as follows: Vn=k V n = k , where V is the volume of the gas, n is the number of moles of the gas, and k is a proportionality constant.

Examples of Avogadros Law Another common example of Avogadro’s law is the deflation of automobile tyres. When the air trapped inside the tyre escapes, the number of moles of air present in the tyre decreases. This results in a decrease in the volume occupied by the gas, causing the tyre to lose its shape and deflate.

Derivation of Avogadro’s Law Avogadro’s law is derived from the ideal gas equation, which is expressed as follows: PV = nRT. Where in, P refers to the pressure exerted by a gas on its container wall. V refers to the volume occupied by gas.

### How does Avogadro’s law apply to everyday life?

Avogadro’s Law in Everyday Life When you blow up a balloon, you are adding molecules of gas into it. The result is that the volume of the balloon increases – and in order to do this, you decrease the number of molecules in your lungs (which decreases their volume)! A bicycle pump does the same thing to a bicycle tire.

### How is Avogadro’s law used?

Avogadro’s Law is in evidence whenever you blow up a balloon. The volume of the balloon increases as you add moles of gas to the balloon by blowing it up. If the container holding the gas is rigid rather than flexible, pressure can be substituted for volume in Avogadro’s Law.

Why is Avogadro’s law directly proportional?

Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
