HEAT ENERGY PROJECT

Definition of Heat Energy

Heat energy it is caused by activity or velocity of molecules in a substance.  

The level of the heat in a substance is the temperature.

Heat has always been confused with temperature. Temperature is a quantitative measure of hotness or coldness. 

How is it done?

In this experiment I’m going to use the solar energy to burn a paper with a magnifying glass.

We take a magnifying glass and a piece of paper. We put the magnifying glass in the sun, and the piece of paper underneath, we have to move the magnifying glass until the point of the sun's rays on the paper is smaller. After a while the temperature of the paper will rise so much that the paper will start to burn.

Why is this happening?

This passes because when the sun rays pass through the magnifier, they concentrate in a single point and a high temperature is produced and that's why it burns.
