• Since we have changed the test date, we will go on to the next subject, Gas Laws. We will only spend 1/2 day now on this concept. We will deal with it later also.
• So I am sending you back to my 1st year webpage so that you can print out and review all the relevant concepts for gas law. So look at GasLaws. Don't be fooled, there is a boat load of reading/reviewing here. Make sure you go to the webpage on Animation (mhhe site) of Gas Laws and Avogadro's Hypothesis.
