Introduction - A dynamic environment of matter and material surrounds man. Since his birth he has been exposed to these changing surroundings. His curiosity to understand his surroundings and the events occurring around him, has led him to systematically enqu..

A system, which can exchange matter as well as energy with the surroundings is called an open system. All reactions carried out in open containers are examples of open systems. Evaporation of water in a beaker or hot coffee in a cup represents an open system. Here vapour of wat..

A system, which can exchange matter as well as energy with the surroundings is called an open system. For e.g., hot coffee in an open flask because it can gain or loose matter and energy with the surroundings. fig 4.1 - Example of open syst..

A 100 mL syringe is taken whose nozzle is plugged or closed by inserting a rubber cork. The plunger is drawn out such that the whole space is occupied by air. When the plunger is pushed back into the syringe we notice that the air inside the syringe decreases i.e., it is compressed. The experiment ..

Early Greek Idea Empedocles (500 - 430 B.C) and Aristotle (384 - 322 B.C) suggested that all matter was made up of four primary elements fire, water, air and earth. Further, the properties of any particular substance were believed to be due to the composition ratio of these four primary..

A system, which can exchange energy but not mass with the surroundings is called a closed system. For example, boiling water in a closed steel vessel is an example of a closed system. The energy can be gained or lost (through the steel walls) but not matter. Similarly, all reac..

Take some crystals of iodine in an evaporating dish. Cover it with a glass funnel, as shown in figure 2.3. Close the tip of the tail of the funnel with some cotton. Heat the dish gently. The space inside the funnel gets filled with purple vapours of iodine. Stop the heating. The purple vapours soli..
