While he was studying the “spring of the air”, Boyle placed a candle nest to the trapped air. He noted that the volume increased.
However, since he was particularly interested in how the volume varied with pressure, he never pursued the phenomenon.
In this lesson, we will study how the volume of a gas varies with its temperature.
A couple of simple and wet expewriments are given. This lesson can be used from middle grade school toadvanced classes in high school.
So at the end of this lesson you, the student will:
Grade school
- be able to explain Charles’ law
- be able gather data from a simple experiment
- take temperature measurements
- calculate the change in volume of a gas
- have drawn a properly labeled line graph using the data from your experiment
- be able to use the graph to explain the type of relationship between volume and temperature.
High School
- be able to explain Charles’ law both verbally and mathematically
- have carefully performed and gathered the data from an experiment
- have plotted a properly labeled graph
- use your graph to:
- calculate the slope intercept equation for the curve
- extrapolate the graph to find the value of T when the volume is zero
- demonstrat the mathematical implications of the Kelvin vs Celsius temperature scales a they apply to Charles’ law
- be able to perform calculations using the relationship developed from the experiment.
