CHEMICAL ENERGY
A voltaic cell harnesses the electrical energy
of a chemical reaction to power a light bulb.
CHEMICAL ENERGY IS THE ENERGY THAT IS STORED IN
CHEMICALS. CHEMICAL ENERGY CAN BE CONVERTED
INTO ELECTRIC, LIGHT AND HEAT ENERGY.
BACK

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

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

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

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

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.

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.
