What factors must you consider to study gas behavior?
The factors we must consider to study gas behavior are:
Pressure (P): the force exerted by gas molecules as they strike a given surface.
Volume (V): the space occupied by gas molecules.
Temperature (T): A measure of how fast gas molecules move (kinetic energy).
Amount (n): Amount in moles of gas molecules.
If any two of the four factors are related, a change in one produces a change in the other. To study the
relationship between any two factors, we must hold the other two factors constant.
To study the effect of:
- temperature on the volume of gas, we have to hold the pressure and amount constant.
- pressure on volume of a gas, we have to hold the temperature and amount constant.
- temperature on the pressure of gas, we have to hold volume and amount of gas constant.
- amount of gas on volume of gas, we have to hold pressure and temperature constant.
