Introduction - We heat raw food to soften it. We freeze water into ice by cooling it in refrigerator. When we boil water in a kettle we observe the steam oozing from the mouth of the kettle. When the cork is difficult to remove, we slightly heat the mouth of the bottle, so that ..

Action of Heat on Sulphur - When heated, sulphur undergoes a series of characteristic changes. Sulphur can melt at two different temperatures. a) If heated rapidly, it melts at 112.8 o C. b) But if heated slowly it will melt only..

Sulphur can melt at two different temperatures. a) If heated rapidly, it melts at 112.8 o C. b) But if heated slowly it will melt only at 118.6 o ..

The heating effect of current is utilised in the electrical heating appliances such as electric iron, room heaters, water heaters, etc. All these heating appliances contain coils of high resistance wire made of nichrome alloy. When these appliances are conne..

Heating Effect of Electric Current - Energy exists in various forms such as mechanical energy, heat energy, chemical energy, electrical energy, light energy and nuclear energy. According to the law of conservation of energy, energy can be transformed from one form to a..

On heating, hydrous crystals lose their water of crystallization and turn into a powder. They are then said to be anhydrous. Sometimes they may also lose their colour. ..
