PURPOSE
This experiment was designed to understand the absorption of heat.
Equipment Setup
1 glass container
4 sheets of acetate paper
Thermometer
100 W light bulb
Graph paper
Wrap one sheet of acetate paper around a clear glass container. Place a thermometer in the glass containers and bring the 100 W light bulb (no lamp shade) to a distance of about 20 cm from the glass container.
Procedure
Record the temperature in the container before the light bulb is turned on. Then turn on the light bulb and take another temperature reading every 5 minutes for 45 minutes.
Repeat the same procedure for the other three sheets of acetate paper, but be sure to allow the thermometer to return to room temperature before you start taking new readings.
Analyzing the Data
1. Using the graph paper, make a plot of temperature (vertical axis) vs. time (horizontal axis) for each of the glass containers. One plot per graph paper please! Be sure you are neat and following the graphing strategies provided with written assignment one. You will hand these graphs in with this written assignment.
2. Now explain your results below. What Conclusions can you reach about the use of colored glass in buildings? In greenhouses? After completing the experimental procedures, make a report for each experiment.
