QUESTION
Why is it critical that the temperature be held constant when applying Boyle’s Law to changing the pressure of a trapped gas?
1. Gas molecules may expand at higher temperatures; this would
change the volume.
2. Changing the temperature causes the gas to behave in non-ideal
fashion.
3. Changing the temperature affects the average particle speed,
which could affect the pressure.
4. Allowing the temperature to drop below 0°C would cause the
trapped gas to no longer follow Boyle’s Law.
