Can electricity
create heat? |

Introduction:
I was looking at
electric heater and wondering how it gets hot? To use the
electric heater we usually plug it to the electricity and turn a
knob. It gradually starts to get hot.
Electricity and heat are two different
types of energy. Does an electric heater convert electrical energy
to heat energy? How does it do that? If electricity produces heat,
why are all the electric wires not hot? and how does the air
conditioning unit creates cold air? |

Project
description:
In this project you will investigate to find out if electricity can
create heat. You will perform experiments to show the heat producing
property of electricity. Identify and get a good understanding of
devices that use electricity to produce heat (Hair Dryer, Iron, Electrical Heater,
...)
As a part of your project, make a device to show that heat producing
properties of electricity can have many industrial applications.
Making a foam cutting tool can be a fun and useful experiment.
Following are two samples of Polystyrene foam cut by foam cutting
tools.
