Pre-Lab Questions
1. In this lab, you will investigate two gas laws that relate pressure, temperature and pressure. In
your own words, explain Charles’ Law. When doing so, explain the relationship that exists
between temperature, volume and pressure in the context of this law. Ensure you discuss
each of those variables.
Charles law shows that heating a gas makes it expand, while cooling it makes it contract.As
temperature rises the gas molecules spread out and takes up more space, when temperature
decreases the molecules slow down which reduces the volume. Charles law also assumes that
the pressure remains constant. If pressure does change it effects the volume.
2. In your own words, describe Boyle’s Law in the context of pressure, volume and temperature.
Ensure that you explain the relationship of each of those variables to one another in the
context of this law.
When volume of a gas is reduced, the gas particles have less space to move which increases
the pressur, when volume expands there is lower pressure.Boyles law states that temperature
remains constant. If temperature changes it would affect pressure and volume. Boyles law
shows us that squeezing a gas into a smaller place will increase the pressure while allowing it
to expand, decreases its pressure as long as the temperature stays the same.

EXPERIMENT 1: CHARLES’ LAW
Introduction Questions
1. In this experiment you will observe changes in volume with changes in temperature. For
temperature and volume to be linearly related to one another, what must be true
about pressure?
The pressure must remain constant.
2. Is it possible to cool a gas down to absolute zero? If you tried to, what obstacles would you
run into?
It is not possible to cool a gas down to absolute zero.There can be many obstacles such as
equipment limitations, also cooling methods rely on energy transfer, there is almost no
energy left to remove at such low temperatures.
3. Suppose during your experiment the temperature goes up, but your observed volume goes
down. Based on your previous responses, you would know this is incorrect and an
experimental error has occurred. What do you think might cause this error? What would you
do to fix this? This would show us that the pressure is not constant, measurement errors, or a
leak in the system. We need to make sure there are no leaks, always maintain constant
pressure, and take multiple measurements.
