CHEMICAL ENERGY

CHEMICAL ENERGY IS THE ENERGY THAT IS STORED IN CHEMICALS. CHEMICAL ENERGY CAN BE CONVERTED INTO ELECTRIC, LIGHT AND HEAT ENERGY.

A voltaic cell harnesses the electrical energy of a chemical reaction to power a light bulb.

BACK NEXT

LIGHT ENERGY

Light is emitted from a source in straight lines and spreads out over a larger and larger area as it travels.Sources of light energy are bulbs,lamps etc.

BACK NEXT

HEAT ENERGY

HEAT IS ALSO A FORM OF ENERGY.EGGS ARE HATCHED DUE TO HEAT ENERGY.STEAM ENGINE USES ENERGY STORED IN THE FORM OF STEAM TO DO WORK.

ELECTRICAL ENERGY

BACK NEXT

ELECTRICAL ENERGY

ELECTRIC CURRENT HAS THE CAPACITY TO DO WORK.THIS ENERGY IS CALLED ELECTRICAL ENERGY . ELECTRICAL BULBS , TUBES, MACHINES,ELECTRICAL ENGINES ETC. USE ELECTRICAL ENERGY .

BACK NEXT

SOLAR ENERGY

Flat plate collectors utilize the sun’s energy to warm a carrier fluid, which in turn provides usable heat to a household solar energy contributes to the growth of plant life (biomass) . SOLAR CELL, SOLAR COOKER ETC. USE SOLAR ENERGY .

Solar Energy, radiant energy produced in the Sun as a result of nuclear fusion reactions.

SOUND ENERGY

SOUND IS ALSO A FORM OF ENERGY BECAUSE IT HAS CAPACITY TO DO WORK . SOUND OF CRACKERS AND HIGH FREQUENCY OF SOUND CAUSES CLUTTERING OF WINDOW PANES .

BACK NEXT

NUCLEAR ENERGY

Nuclear energy can be released in two different ways: by fission (splitting) of a heavy nucleus, or by fusion (combining) of two light nuclei.

BACK NEXT

WIND ENERGY

WIND ENERGY IS OBTAINED THROUGH WIND.WIND MILLS USE WIND ENERGY TO GENERATE POWER ,TO DRAW WATER FROM THE WELLS OR TO RUN FLOUR MILLS.
