a.
The energy transformation in an incandescent bulb.
a.
Explanation of Solution
Introduction:
Transformation of energy is a process in which energy is converted from one form to another.
In an incandescent bulb, electrical energy is converted to heat and light energy. When the current flows throw the wire inside the bulb, it gets heated up and some of the energy converts into heat and light energy.
b.
The energy transformation in clothes dryer.
b.
Explanation of Solution
Introduction:
Transformation of energy is a process in which energy is converted from one form to another.
In clothes dryer, electric energy is converted to kinetic energy, heat energy and sound energy. There is a heating element through which when electricity passes, it converts into heat, kinetic and sound energy.
c.
Energy transformation in digital clock radio.
c.
Explanation of Solution
Introduction:
Transformation of energy is a process in which energy is converted from one form to another.
In digital clock radio, electrical energy is converted to light and sound energy. When electricity passes, it converts into light which can be seen when the time is visible in digital display. The energy also gets converted to sound energy.
d.
Transformation of energy in hand held flash.
d.
Explanation of Solution
Introduction:
Transformation of energy is a process in which energy is converted from one form to another.
In hand held flash, chemical energy stored in the battery gets converted to electrical energy which in turn is converted into light and thermal energy.
