What it really Boyles down to

Today we started by quickly reviewing Dalton's Law and Boyle's Law, with a couple more gas chamber experiments. he sucked all of the air out of the container (after realizing he needed to attache the hose) and made shaving cream get big, unfortunately he stopped it before it made a mess. He also did an old marshmallow which was rather uneventful.

Then we went on to discuss conversion between temperatures of celcius and kelvin because it is necessary to know for formulas. The reason you need to know the Kelvin temperature is because if you use celcius you may end up with correct calculations stating that you ave negative density, which i hope all of you know is "impossible" according to Mr. Lieberman. To convert celcius to Kelvin all you need to do is add 273 degrees to the celcius measurement.

Then as we continued our notes we went on to Charles' law, which states: The volume of each gas is directly proportional to temperature. V=bT where b is a constant and V1/T1=V2/T2. This means that the original volume over temperature will be equal to the new volume over temperature. To explain this to us he showed us a quick experiment by heating to small flasks with water until they boiled, he then stuck a balloon on top of one which was still boiling and the balloon filled as the gas expanded. he stuck another balloon on top of the other right after removing it fro the heater, the balloon was quickly sucked into the flask because of the rapid change in temperature and the fast reduction of volume.


Next D Liebs quickly explained Avogadro's law which states: Volume is directly proportional to the number of moles of gas. To show this he simply blew up a balloon and let go, letting it soar around and land on Alex's desk. This demonstrates that as moles of air are released there is less and less volume and pressure to keep the balloon inflated, so it eventually collapses. then there is the infamous combined gas law which is P1V1/T1=P2V2/T2 this can be used to apply all forces to one equation instead of several different ones.

There was also a sheet to pick up at the front when we walked in, that sheet is homework and is due come test day. Speaking of which is next friday, the friday right before break. Also, everyone check out the little map thing to the right, people all over the world have seen our blog!

Also since Ben never posted any hilarious pics that im sure everyone wants, here is zoë, looking as happy as a person being vacuum sealed.

And now the next scribe will be... OH MY GOODNESS... Deena M.
