Have you ever wondered why a balloon inflates when filled with air? Or why does a hot air balloon rise? The answers lie in the fundamental principles that govern the behaviour of gases, known as the gas laws. In this blog post, we’ll embark on a scientific journey to explore the three pillars of gas law: Boyle’s Law, Charles’s Law, and Avogadro’s Law.
Boyle’s Law: A Matter of Pressure and Volume
Imagine trapping a certain amount of air in a balloon and squeezing it. What happens? The balloon shrinks, right? This observation forms the basis of Boyle’s Law, which states that at constant temperature, the pressure of a gas is inversely proportional to its volume. In simpler terms, if you squeeze the balloon (decrease volume), the pressure inside increases to compensate. Conversely, if you release the balloon (increase volume), the pressure decreases.
Charles’s Law: The Temperature Connection
Now, let’s heat that shrunken balloon. What do you observe? It inflates again! This phenomenon is explained by Charles’s Law, which states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature. In other words, as the temperature increases, the gas molecules move faster, requiring more space, and hence the balloon expands. Conversely, if you cool the balloon, the molecules slow down, occupying less space, and the balloon shrinks.
Avogadro’s Law: Counting Gas Molecules
Have you ever filled two balloons with the same amount of gas but used different types of gas, like helium and oxygen? They might not inflate to the same size! This is because Avogadro’s Law comes into play. It states that at constant pressure and temperature, the volume of a gas is directly proportional to the number of gas molecules present. So, even if you have the same amount of gas in two balloons, if one gas has more molecules than the other (like helium compared to oxygen), it will occupy a larger volume.
