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 product of the volu..

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 proportional to the pressure (P) at constant temperature. Math..

Introduction - The branch of chemistry, which deals with energy changes during various physical processes and chemical reactions, is called chemical energetics. All chemical reactions are normally accompanied by energy changes. These energy changes take place because energy is needed to break chemi..

Soddy and Fajan summarised the a and b - particle emission in the form of the law known as Group Displacement Law. "The emission of a - particle by an element results in the formation of a new element which lies two places to the left of the parent element and the emis..

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) = 273 = 450 K Substitu..

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 2 =? Applying Boyle's La..

According to third law of thermodynamic it is only at OK that true crystals passes perfect order of arrangement of atoms in pure crystals. But with rise in temperature some derivations from complete order takes place. Presence of impurities also adds to disorder. "Any departure from perfe..
