gas laws lab

     The three gas laws are; Charles' law, Boyle's law, Gay-Lussacs law. The PTV chart is is a basic way to remember what happens to the Pressure, Temperature, and Volume of the gas or gasses.  


Charles' law
     This law states that if volume increases so will the temperature of the gas.  One example of this is to get an egg out of a bottle. when the egg gets stuck reheat the bottle and the pressure will be greater inside the bottle thus "pushing" the egg out of the bottle. a real world example would be like when my football is outside  when it is cold it appears to have less air in it than it did before.  Because when it gets colder the air molecules compress making it appear to have less air in it than it did before.


Boyle's law

     This law states that when pressure goes up volume goes down.  One example of this is was when air was added to the bottle to increase the pressure and we looked at the pressure gauge.  one real world example of this is a syringe.  when you pull up on the plunger it increases the potential volume of the container and it fills up with liquid attempting to re-pressurize itself.


Gay-Lussac's law
     This law states that when pressure goes up so does the volume.  One example of this is when we pressurized the inside of the bottle and watched the temperature gauge go up as we pressurized it.  one real world example of this is a car tire. as you are driving it heats up and thus gives it more volume and a higher temperature.
