Frank is about to check my blog

At this point in my life i am thinking of what to do with the knowledge i have gained in this class. this has been a great year and this post is totally not just to say i have 4 in gas laws. (i thought we were doing another one for later in this week)

ideal gas law

The idel gas law is used when you need to find a single variable out of the 4 when the others are given. Because this law uses R,the universal gas constant, the pressure must be in atm, the temp. in Kelvin, and the Volume in liters. Also mass must be in mols. This equation is the derogatory equation for all the others that we have learned.

Charles law / Avagadros law

Charles law: V1/T1=V2/T2

Charles law is another gas law based of the ideal gas equation. This time however is pertains to the direct relationship of temperature and volume. If one is increased then the other must also increase at a fairly steady rate.

Avagadros law: V1/n1=V2/n2

Avacados law is the third gas law we are working with and tells us about the relationship between Moles and volume. Like charles law there is a direct relationship between the two. Unlike any other law so far, this law uses moles. Making us have to use stoich in a couple more situations. This could pose a problem on quizzes  because steps could be skipped or not remembered.

Boyles Laws

Boyles law: P1V1=P2V2

Boyles law is the first gas law we have learned and it shows the relation between pressure and volume. So the law is showing us that as long as the temperature of the gas is constant then Volume and pressure have an inverse relationship for when one of the variables change.

Heat capacity of metal lab

Our class did an experiment to find the specific heat of the metals Cu and Pb. To do this we first heated up our metals using a boiling water bath with the metals in them. This rose the heat of the metal to around 100 degrees (we checked for the exact temp) and then we had water at room temperature wich we were going to dump the metal into. This gave us the known variables of M-water, M-metal, Specific heat of water, Temperature of both before and after, leaving the only unknown variable by the end of the lab to be the specific heat of the metal.

energy and phase change

Our new unit is over phase change and the energy involved with that phase change. One of the bic componenets is using the equation Q=MC(delta)T. Another big component to this unit is the Phase change diagrams and how to read them.

Biodiesel boats

Today wall be a day that will be forever set in history books as the most amazing day of all time. Our class has finally put our Chik fill ah biodiesel on our boats and sped across the finish line. Sadly my partner was not there to help make the boat but we did work together to make the fuel.
