FC: Ideal Gases In The Real World | McKenzie Young

1: Charles's Law V1/T1=V2/T2 Also known as the law of volumes, this law states that assuming the pressure remains constant, the volume and absolute temperature are directly proportional. | An everyday example of Charles's law is a life raft. A slightly inflated raft will begin to swell if it is left out in the sun too long due to the increasing temperatures.

2: Boyle's Law P1V1=P2V2 This law states that the volume of a gas in inversely proportional to the pressure applied to it. | En everyday example of Boyle's law is when deep sea fish are brought up to the surface. The water pressure decreases making the volume of the gases inside their bodies increase making their bladders, cells, and membranes burst.

3: Gay-Lussac's Law P1/T1=P2/T2 This law states that the pressure of a sample of gas, at a constant volume, is directly proportional to its temperature in Kelvin. | An everyday example of Gay-Lussac's law is when a car tire explodes. During the hot summer months more car tires explode because the pressure of the gas inside the tire increases with the increasing temperature.

4: Avogadro's Law V1/n1=V2/n2 This law states for a gas, at a constant temperature and pressure, its volume is directly proportional to the number of moles of gas. | An everyday example of Avogadro's law is breathing. The volume increases as air is inhaled. The volume decreases as air is exhaled.

5: Combined Gas Law P1V1/T1=P2V2/T2 This law contains Charles's, Boyle's, and Gay-Lussac's law. This law states the the pressure and volume of a gas are inversely proportional to each other, but directly proportional to the temperature of the gas. An everyday example of the Combined Gas law is a weather balloon. The balloon begins at the Earth at a certain pressure, temperature, and volume and upon its accent all three variables change in response to the surroundings.

6: Ideal Gas Law PV=nRT This is the equation of state of a hypothetical ideal gas. In a perfect or ideal gas the change in density is directly proportional to the change of temperature and pressure. An everyday example of the Ideal Gas law is the internal combustion engine. The combustion of gas creates CO2 and other gases which expand in the cylinders of the engine, pushing the pistons to convert chemical energy into mechanical work. Since the volume is fixed, the increase in temperature causes an increase in pressure.

7: Amonton's Law P1/P2=T1/T2 This law states that the pressure of a gas is directly proportional to the temperature. | An everyday example of Amonton's law is throwing an aerosol can into a fire. The temperature increases causing the pressure to increase inside the can causing it to explode.

8: Dalton's Law of Partial Pressures. Pt=P1+P2+P3+.... This law states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the various components. | An everyday example of Dalton's law is growing glass fibers. Mixed gases, such as silane and oxygen, are put in a high vacuum to do this process.
