Pressure, Volume, Temperature, Number of moles!!







Another awesome day Honor chemistry 7th period!! oh yeah
Today we learned relationship between Pressure, Volume, Temperature, and Number of moles by looking at three formulas.
The first one was Boyles' Law

Therefore

As pressure increase volume decrease and when volume in crease pressure decrease.


a constant(k) stay same and pressure and volume are inversely proportional

The next formula was Charles' Law


As Temperature increase volume increase, so volume is directly proportional to temperature
o
B = a constant
Mr. Liebeman show a demo of this formula
He had two beakers and two balloons, and he heat one of them and put the other one into liquid nitrogen. As you can see in this picture the ballon on right side blowed up, because the temperature of air inside of ballon increase and it increase volume. On left side the ballon stuck inside of beaker, because this one was put in liquid nitrogen and cooled, so the air inside of beaker decrease volume.
The last formula was Avogadro's Law


a = a constant

Volume is directly proportional to the number of moles

Overall if we combined these formula to one formula


Whenever each one of value stay same we can cancel out

once again I really think 7th period Honors Chemistry is cooler than any other class haha

tonight's homework is Gas law sheet, and NEXT SCRIBE IS.......JOE R yeahhhh
