electric appliance that convert electrial energy to mechanical energy

Energy can be defined as the ability to do work. A good source of energy would be the one which would: do a large amount of work per unit volume or mass be easily accessible be easy to store and transport and be economical Fossil Fuel Fossil fuel is a hydrocarbon de..

Rating of Electrical Appliances - Generally electrical appliances such as an electric bulb, geyser, heater, etc. are rated with power and voltage. If a bulb is rated 100W - 250V, it means that when a bulb is lit on a 250V supply, it consumes 100 W o..

There are two types of heat engines: external combustion engines and internal combustion engines. Steam engine is an example of external combustion engine. In such an engine, the fuel is burnt outside the working portion of the engine. A heat engine consists essentially of the following parts: i)..

Geothermal energy can be used to generate electricity in various ways. If dry steam comes out of the surface of the earth, it can be used directly to turn turbines connected to generators. The world's largest geothermal electric power plant, at Geysers Steam Field,..

fig. 1.2 - Energy transfer and energy transformation Examples of energy transformation 1. Photosynthesis - in which green plants transform radiant solar energy into chemical energy that gets stored as potential energy in carbohydrates. 2. ..

. (iii) Loss of one a - particle. decrease in mass number is 4 and decrease in atomic number is 2. Example 7:- Calculate the energy released when 1 kg mass is completely converted to energy (C = 3 x 10 8 m/s). Suggested Answer:- Example 8..

Digestion - breaking down food into simpler forms. Digestion is both and chemical . The digestion may take place outside cells ( extracellular ) or within the cells ( intracellular ). Absorption - Taking in of food in the soluble forms into the tissues. The absorption may be passive (without ..

Energy changes in chemical reactions can also take place in forms other than heat, such as light, electricity, mechanical energy, etc. Some common examples are: The burning of petrol or diesel in motor engines of cars, trucks, tractors or buses produces ..

Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical ..
