The most important use of the ideal gas law in daily life is in estimating the amount of ventilation a building needs for human use; another use is in estimating cabin pressurization in airplanes. In any closed environment with many people inside, the amount of air that gets through the walls may be insufficient. The amount of oxygen in a given volume is determined by this law.Know More
The ideal gas laws give the relationships between pressure, temperature and volume for any mix of ideal gases. Unfortunately, only the noble gases such as helium and neon are actually close to ideal, but the ideal gas law is still a close enough approximation for many purposes.
In any environment where the intake of oxygen and the release of carbon dioxide is likely to be insufficient for the number of people inside, some type of ventilation must be installed. This ventilation must be lesser or greater depending on the number of people and their level of activity. In sealed environments such as an airplane at cruising altitude, air must be pumped in at a greater pressure than the outside pressure. The ideal gas laws, combined with information about the average pressure and percent of oxygen in the air, tell how much oxygen needs to be brought in to keep the air fresh and sufficiently oxygenated.Learn more about States of Matter
Henry's law, formulated by chemist William Henry in 1803, states, "at a constant temperature, the amount of a given gas that dissolves in a liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid." The solubility of a gas in a liquid depends directly on the partial pressure of the gas over the liquid.Full Answer >
Dreams possess the capacity to incorporate memories from your daily life, such as a person you've met recently or someone you've known your whole life, but the meaning and use of this phenomenon is unknown. Most dreams just piece together bits of memories.Full Answer >
The combined gas law applies any time there is a closed system with a fixed amount of gas, including the tires on a car. It expresses the behavior of the gas when temperature, volume or pressure changes, according to About.com.Full Answer >
Daily life makes use of the Pythagorean theorem in various ways, such as determining the viewing size of a television, which is sometimes a factor used in purchasing decisions. Given the length and height of the screen, the diagonal viewing area can be determined with the theorem.Full Answer >
