![]() ![]() The gas liberating expands because of high temperatures in the oven. When bread and cakes are baked, this conversion is accelerated. It converts sugars in the dough to carbon dioxide gas. Yeast is a leavening agent belonging to fungi. Our delicious bakery products like bread, cakes would not be spongy and soft without yeast. We can see Charles's law in our kitchens also. A helium balloon shrinks in a cold environment. When the same balloon is brought back to a warm room, it regains its original shape. If you take a balloon out in a snowy day, it crumbles. Like tyres, helium balloons also experience expansion and contraction with change in surrounding temperature. Seasonal expansion and contraction of tyres Helium balloon While in hot days, the air expands with temperature. In winter due to low temperatures, the air inside a tyre gets cooler, and they shrink. This unusual behaviour is because of Charles's law. Tyres of untouched vehicles get deflated during freezing winter days while get inflated in hot summer days. The ball is inflated and dents are fixed. On immersion, the temperature of the air inside the ball increases, and as per Charles's law, the air expands. A common method to fix this dented ball is to immerse the ball into warm water. A ping-pong ball with racketsĪ common problem with ping-pong balls is they can get a dent when expose to a strong blow or pressure. Ping-pong or table tennis is an international sport famous in China, Austria, Belarus, Germany, and Hong Kong, to name but a few. In a hot climate, The temperature of the air inside swim floats increases, and they get overinflated. The reverse phenomenon is observed during hot summer days when water is much warmer. The air in swim floats shrinks because of a decrease in temperature of the air inside floats. Pool floats are filled with air that makes them much less dense than water. Pool floatsĪs a toddler, we all have used a pool float during swimming lessons. It shrinks the lungs and physical activities like jogging becomes difficult in freezing winter days. Hence, the volume of the air decreases with the temperature. According to Charles's law states volume is directly proportional to temperature. As a consequent, the temperature of the air inside the body also decreases. In winters, the temperature of air decreases. Air flows in when the lungs expand and flows out when they contract. The human lungs are spongy air-filled organs play an important role in respiration. The buoyant force pushes the lighter envelope up in the air, and it flies. This makes the envelope lighter than the atmospheric air surrounding it. As the temperature of the air increases, the volume of the air also increases and consequently, the density decreases. This hot air expands as per Charles's law. On ignition of the fuel, the air inside the envelope heats up. It consists of a bag or an envelope, a basket to carry passengers, and a fuel source like propane. The working principle of an air balloon is simple. In fact, Charles himself was a balloonist and was one of the few who flew the first hydrogen balloon at the Champ de Mars in Paris. Hot air balloonĪn air balloon is a classic example of Charles's law. Here are some real-life examples of the law. Although the discovery of the law goes back to the late 1700s, we can see its applications and examples in our everyday activities. He found through his experiment the volume of a gas increases linearly with an increase in the temperature. The law is named after Jacques Charles, who was a French inventor and scientist. ![]() Charles's law is a gas law relates volume to temperature. ![]()
