Question:  How are pressure, temperature, and volume related in a gas?

Purpose:

The purpose of this lab was to measure the pressure, volume, and temperature of gases and observe how they are affected and relate to each other through the use of Boyle's Law and Gay-Lussac's Law at a constant volume.  

The distance between the molecules in a gas are spread apart from each other, therefore causing less collisions between molecules allowing for the gas to easily be compressed.  Gas pressure is related to the frequency of gas molecules bouncing off one another as well as the container/space they are located in.  Decreasing the volume, increases the pressure.  If there is an increase in temperature, this causes the gas molecules to expand and move around more freely which also results in an increase in pressure because there will be more collisions occurring between molecules.  The relationship between these factors will be studied in this experiment.
