Examples of Avogadro's law in everyday life?

Answer 1

Avogadro's Law: Doubling the number of moles of gas doubles its volume, if temperature and pressure aren't changed.

• A flat tire takes up less space than an inflated tire.
• Lungs expand as they fill with air. Exhaling decreases the volume of the lungs.
• A balloon filled with helium weighs much less than an identical balloon filled with air. (Avogadro's Law implies that equal volumes contain equal numbers of molecules, when pressure and temperature are held constant. Since both balloons contain the same number of molecules, and since helium atoms have lower mass than either oxygen molecules or nitrogen molecules in air, the helium balloon is lighter.)
• Wet air is less dense than moist air (see the FAQ on gases for an explanation).
• Or simply, all in all, it's just a matter of quantity of gas. (Quantity refers to it's moles). And as the quantity increases, the volume of it's containre, increases to. :)
