Chemistry Module 9, Gas Laws
Lesson 1. Boyle’s Law
Introduction
Air is all around us. We breathe in the air so that our body can receive adequate
supply of oxygen gas. Our lungs expand as they fill with air and take in oxygen, and relax
as they release carbon dioxide. Plants in turn, use up the carbon dioxide during the process
of photosynthesis to manufacture sugars. Life as we know it would not have been possible
without the life-sustaining gases found in the atmosphere
Like breathing, many other human activities involve gases. When air is pumped into
a bicycle or automobile tire, a mixture of gases is compressed into a small volume. Helium
gas make toy balloons float. Gas used to fill rubber lifeboats and vests exerts pressure on
its containers, giving them rigidity and shape.
