Boyle's Law In the 1700's a number of people investigated gas behavior in the laboratory. Robert Boyle investigated the relationship between the volume of a dry ideal gas and its pressure. Since there are four variables that can be altered in a gas sample, in order to investigate how one variable will affect another, all other variables must be held constant or fixed. Boyle fixed the amount of gas and its temperature during his investigation. …showed first 75 words of 1078 total…

If a gas possessing an odor such as Ammonia were allowed to escape an open bottle, it would not take but a few seconds for the detectable odor of Ammonia to be detected throughout the room. Ammonia gas molecules having a great deal of space between the particles of Ammonia and air could travel at a faster rate.
