The Theory of Gases

The Theory of Gases describes how gases behave based on the idea that they are made up of tiny particles moving rapidly in all directions. These particles are spread out and constantly colliding with each other and their container’s walls. These collisions create pressure, and their speed relates to temperature. When temperature rises, particles move faster, increasing pressure if volume and amount stay the same. Conversely, if you change the container size or amount of gas, pressure and volume adjust accordingly. This theory helps explain phenomena like why balloons expand in heat and engines operate efficiently.
