Discuss at least 3 real life application of gas laws.
All gases, despite their difference in chemical properties, obey certain laws. These are called the Gas Laws. Many years ago, specifically in the end of the 18th Century, Scientists discovered that the pressure, volume and temperature of a sample gas can be measured and can hold approximation for all gases in general. Some Scientists took part and flourished in the idea of gas laws. The following scientists are Robert Boyle, Jacques Charles, Joseph Louis Gay-Lussac, etc. which were well-known for their contribution which helped subsequent generations to the present.
1. Boyle's Law
Pumping gas into a tire.
The tire's pressure is increasing when pumped with gas because the gas is compressed inside the tire. The gas molecules inside the tire starts to push against the walls of the tire making the tire tighter. The Boyle's law is applicable in this situation because it was stated in the law that pressure varies inversely with volume at constant temperature. In this real life situation, as you pump more air inside the tire, the pressure increases because there is less space for the air molecules to move.
2. Charles' Law
Helium balloon in cold and warm environment.
The balloons expand when they are exposed at warm environment and deflate when they got exposed with the cold environment. This is because the heat stimulates the movements of the particles and increases the kinetic energy thus, the particles occupy larger space. Meanwhile, if the balloons were exposed in cold environment, the low temperature causes the particles to move at slow rate. Therefore, particles do not occupy large space. The Charles' law was applied in this situation because in this law, the volume and temperature were directly proportional. Meaning, if the temperature increases, the volume also increases and vice versa.
3. Avogadro's Law
Inflating a balloon using the air from the lungs.
By inflating the balloon you add gas molecules inside it and the gas molecules in your lungs decreases. As gas molecules from your lungs decreases the volume of your lungs also decrease. As the gas molecules inside the balloon increases the volume of the balloon also increases.
4. Combined Gas Laws
Scuba Diving
Mixed or combined gas law is a combination of the three gas laws which are the Boyle's law, Charles' law, and Gay-Lussac's law which states that the ratio of the product of volume, pressure, and temperature of a gas stays the same. Example of real-life application of combined gas law goes with scuba diving. The lungs serve as the container which holds the gas for scuba divers. As the scuba divers dive, water pressure rise because the pressure in water is greater than the pressure in air. They should make changes to keep up the correct weight balance between their lungs and the water. This change should occur continuously and scuba divers should breathe out quickly so that the gas in the lungs escape.
We hope you learned something from this post. Stay tuned for more information and see you next year! -Group Silver
