problems based on combined gas law

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..

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 constan..

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 Substitution the valu..

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 Law P 1 ..

When substances react, they do so by following certain laws. These laws are called the laws of chemical combination. These formed the basis of Dalton's atomic theory of matt..

Law of Combination of Resistance in Parallel - Connect two resistors 'R 1 ' and 'R 2 ' in parallel to one another between the points A and B. Connect this combination to a battery of potential 'V..

Law of Combination of Resistors in Series - Let us consider two resistances 'R 1 ' and 'R 2 ' connected in series. A battery of 'V' volts is applied to the ends of this series combination. Let us name the potential difference across R 1 as V 1 , and that across R 2 as ..

Connect two resistors 'R 1 ' and 'R 2 ' in parallel to one another between the points A and B. Connect this combination to a battery of potential 'V..

The study of reactions is one of the important areas of Chemistry. There are many aspects of a reaction like the rate of reaction, energy absorbed or evolved, mechanism of a reaction that can be evaluated only with weight and volume relationships. A study of reactions is possible by understanding t..

Let us consider two resistances 'R 1 ' and 'R 2 ' connected in series. A battery of 'V' volts is applied to the ends of this series combination. Let us name the potential difference across R 1 as V 1 , and that across R 2 as V 2 . Since 'V' represents energy, according to the law..
