Scientists in the late 1800’s noted relationships between many of the state variables related to gases (pressure, volume, temperature), and the number of gas particles in the sample being studied. They knew that it was easier to study relationships if they varied only two parameters at a time and "fixed" (held constant) the others. Use the simulation to explore these relationships.

Variables Constant Parameters Relationship Proportionality (see hint below)

pressure, volume directly proportional inversely proportional
volume, temperature directly proportional inversely proportional
volume, number of gas particles directly proportional inversely proportional

Hint: A pair of variables is directly proportional when they vary in the same way (one increases and the other also increases). A pair of variables is inversely proportional when they vary in opposite ways (one increases and the other decreases). Label each of your relationships in the table above as directly or inversely proportional.
