.Since it's hard to exactly describe a real gas, people created the concept of an Ideal gas as an approximation that helps us model and predict the behavior of real gases. The term ideal gas refers to a hypothetical gas composed of molecules which follow a few rules: Ideal gas molecules do not attract or repel each other and Ideal gas molecules themselves take up no volume. The pressure, P, volume V, and temperature T of an ideal gas are related by a simple formula called the ideal gas law. Where P is the pressure of the gas, V is the volume taken up by the gas, T is the temperature of the gas, R is the gas constant, and n is the number of moles of the gas. https://www.khanacademy.org/science/physics/thermodynamics/temp-kinetic-theory-ideal-gas-law/a/what-is-the-ideal-gas-law REAL WORLD EXAMPLE: When a balloon is blown up, the temperature and pressure are constant while the volume increases but the temperature of the air particles in the balloon are hotter than the air outside the balloon. Because the air in the balloon is at a higher constant temperature than the outside air, the balloon rises. https://sites.google.com/site/kingsacademy04/the-ideal-gas-law/applications
VIEW MOREIn the mid 1600's, Robert Boyle studied the relationship between the pressure p and the volume V of a confined gas held at a constant temperature. Boyle observed that the product of the pressure and volume are observed to be nearly constant. The product of pressure and volume is exactly a constant for an ideal gas. This relationship between pressure and volume is called Boyle's Law in his honor. REAL WORLD EXAMPLE: Every balloon has a certain volume depending on how much it is blown up. When someone sits on a balloon or attempts to pop it in any certain way, the pressure on the balloon is increasing therefore decreasing the volume in the balloon until it cannot release anymore air and then it pops. Boyle's Law states that when the pressure increases at a constant temperature, the volume decreases accordingly so because the temperature in this example does not change but instead the pressure increases, the volume has to decrease in the small space that is the balloon leaving it's only option to be releasing the gas in the balloon by popping. http://www.cbsenext.com/cbse-topics/boyle%E2%80%99s-law-and-real-life-examples#
VIEW MOREIf the temperature of a container is increased, the pressure increases. If the temperature of a container is decreased, the pressure decreases. Why? Suppose the temperature is increased. This means gas molecules will move faster and they will impact the container walls more often. This means the gas pressure inside the container will increase, since the container has rigid walls (volume stays constant). Gay-Lussac's Law is a direct mathematical relationship. This means there are two connected values and when one (either P or T) goes up, the other (either P or T) also increases. The constant K remains the same value. http://www.chemteam.info/GasLaw/Gas-Gay-Lussac.html REAL WORLD EXAMPLE: A real world example of Gay Lussac’s law is heating an aerosol can. If you heat an aerosol can, the temperature increases while the air is still in the can without anywhere to go therefore increasing the pressure inside the can. Gay lussac’s law states that if the temperature increases, pressure increases accordingly while the volume stays constant. Because the temperature is increasing while you heat the can, the pressure must increasing causing the can to eventually explode because the pressure becomes too much for the can to hold. https://socratic.org/questions/what-is-a-real-life-application-that-demonstrates-gay-lussac-s-gas-law
VIEW MOREIncreasing the temperature of a volume of gas causes individual gas molecules to move faster. As the molecules move faster, they encounter the walls of the container more often and with more force. In an inflexible container, the more frequent and forceful collisions result in higher pressure. However, if the container volume is adjustable, the volume will increase, and the pressure will remain the same. Charles’ Law is the formal description of this relationship, allowing change in volume to be calculated if the temperature change is known. http://scienceprimer.com/charles-law REAL WORLD EXAMPLE: In the winter when it is cold outside, your tires deflate, or lose air pressure, and the opposite occurs in the summer when you notice that your tires are over inflating. This happens because of the relationship between temperature and volume as explained in charles law. When it is cold outside the volume of air in your tires decreases directly with the temperature. When it is hot outside the volume of air in your tires increases directly with the temperature leaving them to over inflate from the low volume in the winter. https://socratic.org/questions/what-are-some-examples-of-charles-law-1
