Make a power point presentation (maximum 20 slide) to show that black colour absorb more heat than white
Answers
The contents of the slides should be as follows :
1.) Slide number one should contain the title and the subtitle of the experiment which is :
Proof that black colour absorbs more heat than a white surface.
2.) Slide number two should contain a brief explanation of what we mean by heat absorption.
Heat absorption is whereby a surface acquires heat from a source of heat.
3.) Slide number three should contain an explanation of heat absorption by the white and the black surface.
Black surfaces absorb more heat than white surfaces since most of the heat that falls on the white surface is reflected away.
4.) The fourth slide should contain examples of both black and white surfaces.
An example of a black surface could be a container painted black and for a white surface is a container painted white.
5.) The fifth slide should contain an example of an experiment to verify this.
The experiment will be obtaining two containers one painted white and the other one black then filling them with water and putting them under the sun. We later check the temperatures of the water after some time.
6.) For slide 6 up to 19 we should go through the experiment listing the apparatus and listing down the observations.
7.) For slide 20 we give the conclusion from the observations
The water in the container painted black is hotter than the water inside the container painted white. Therefore black colour absorbs more heat than white colour.
