numericals based on gas laws

Important relationships - 1 mole of an atom = 1 gram atomic weight of an atom 1 mole of a molecule = 1 gram molecular weight of molecule 1 mole of a gas = 22.4 liters of gas at STP 1 mole of a substance = 6.023 x 10 2 3 , atoms, molecules or ions Molecular weight = 2 x Vapor den..

The study of behaviour of gases has led to the formulation of a few important generalisations called as Gas Laws..

Boyle's Law Robert Boyle proposed this law in the year 1662, giving the relationship between pressure and volume of given mass of a gas at constant temperature. This law states that volume (V) of a given mass of gas is inversely proport..

Gas Laws - Boyle's Law - The volume of a given mass of a dry gas is inversely proportional to its pressure, temperature remaining constant. Robert Boyle (1627 - 1691) discovered this law in 1662 and it was named after him. It can be restated as "The..

Jacques Alexander Cesar Charles, a French chemist, discovered in 1787, that at a constant pressure, with rise in temperature, carbon dioxide, hydrogen, oxygen and nitrogen, all expanded at constant rat..

A given mass of a gas occupies 240 ml at 800 mm of Hg. What volume will the gas occupy if the pressure is increased to 1200 mm of Hg, temperature remaining constan..

Problems Based on Charles' Law - Example 1:- A given mass of a gas occupies 960 ml at 27 o C. What volume will it occupy if the temperature is raised to 177 o C, pressure remaining constant. Solution:- V 1 = 960 ml V 2 =? T 1 = (27 o C + 273) = 300 K T 2 = (177 o C) = ..

Problems Based on Boyle's Law - Example 1: A given mass of a gas occupies 240 ml at 800 mm of Hg. What volume will the gas occupy if the pressure is increased to 1200 mm of Hg, temperature remaining constant? Solution:- P 1 = 800 mm P 2 =1200 mm V 1 =240 ml V..

Summary - Gases are different from solids and liquids. They have no definite shape or volume. When pressure is applied, a gas contracts and when pressure is released, the gas expands. Gases can move in all directions and completely diffuse with other gases to form a homogenous m..

Gas is one of the three states of matter - the other two being liquid and solid. A gas differs from a solid and a liquid in a number of ways. A gas fills entire space available to it and therefore it has no definite shape or volum..
