A balloon is inflated with helium gas at room temperature of 25 °C and at 1 bar pressure when its initial volume is 2.27L and allowed to rise in air.
Given : P1 = Initial pressure = 1 bar V1 = Initial volume = 2.27 L P2 = Final pressure = 0.3 bar To find : V2 = Final volume Formula : P1V1 = P2V2 (at constant...

At constant temperature and pressure, two litres of hydrogen gas react with one litre of oxygen gas to produce two litres of water vapour.
(D) law of gaseous volumes \(\underset{2L}{H_2(g)}+\underset{2L}{O_2(g)}\longrightarrow \underset{2L}{H_2O(g)}\) Gay-Lussac's states that "At same temperature and pressure, when gases combine or produced in a chemical reaction, they do so in a simple ratio by volume. Here, \(H_2\), \(O_2\) and \(H_2O(g)\) are...
