Answers
Answer:
In an electric heater, oven, geyser, toaster etc., the electrical energy changes into heat energy.
(ii) An electric generator.
(iii) Tube eight of bulbs.
(iv) Burning of wood, coal etc.
(v) Fire crackers burst
Answer:
1)(i) In an electric heater, oven, geyser, toaster etc., the electrical energy changes into heat energy.
2)the motor in today's standard power drills.
the motor in today's standard power saws.
the motor in an electric tooth brushes.
the engine of an electric car.
3)Electrical energy conversion to light and heat. ... In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).
4)Coal is burned at a power plant. The chemical energy released as the coal is burned heats water and turns it into steam. ...
Gasoline is burned in a car engine. ...
A furnace burns natural gas in a chemical reaction. ...
Hand warmers used for hunting operate by chemical reaction. ...
A butane torch burns butane gas.
5)Coal: Combustion reaction converts chemical energy into light and heat.
Wood: Combustion reaction converts chemical energy into light and heat.
Petroleum: Can be burned to release light and heat or changed into another form of chemical energy, such as gasoline.
