Moles Avogadros Law

For cases where the number of moles of gas is changed from an initial amount to another amount (at constant T and P), we can represent Avogadro s law as 

The relationship between volume V and number of moles n. As the number of moles is increased from 1 to 2 (a to b), the volume doubles. When the number of moles is tripled (c), the volume is also tripled. The temperature and pressure remain the same in these cases. 

Light a candle and let some wax drip onto the bottom of a glass that is taller than the candle. Blow out the candle and stick the candle to the glass before the wax solidifies. 

Add water to the glass until the candle is about half-submerged. Do not get the wick of the candle wet. 

Light the candle. Take a test tube that is wider than the candle and quickly place it over the candle, submerging the opening of the test tube. What happens Make careful observations.
