Intermolecule Forces Lab

This is a power point about 6 alcohol's and what their evaporation rates are. We have graphs showing the audience what alcohol was the fastest evaporation rate and an explanation of the graph.

Remebering: What I did in Chemistry is:

1. Mole Calculations,Popcorn lab and % of water lab
2. AgNo3 + Cu Lab
3.  Gas Behavior Lab

What is important about it:

Each blog was interesting to write and learn whats new in the world of biology and just a new insight of the world of Chemistry.

Applying:

I could apply this in everyday life. Biology is very important with what I want to become. I want be become a nurse practioner so this field of science is essential to medical school. Also I think chemistry is cool when we dont have to use the mole.

Evaluating:

How I did this 3rd quarter was good. I enjoyed all the labs we did. I really didn't like the mole maily because I'm not good at math. But all the chemistry expriments were extreamily fun!

Creating:

Next quarter I could put some youtube videos, websites, and just more visual effects to my blogs to give a further explanition of what we are studing. Also I need to get better at writing in my blogs.  I have everything in my head but writing it it comes out wrong but I am trying.

Gas Behavior Lab

We have been working on 3 labs. All three were very fun lab except for the fact that we had a few technical difficulties while working through these labs. Our first lab was a Volume vs Pressure, Pressure vs Temperature and lastly Temperature vs Volume. 

Our 1st lab was Volume vs. Pressure. What we did was stack books on a syringe with the red pressure blocks on top, but this was the way we tested the volume by how much pressure we can put on it. We got up to six books. and the put them on the plunger looking thing. This was a fun experiment. As you can see with the graph you can see the stats of what has been happening.  

This is the plunger looking thing that we put the books on. 

6 BOOKS WOOO!!!

Our next lab was Temperature vs Volume this is where we had a test-tube hooked up to to a temperature probe and placed them in a tube of ice (0'C) and HOT bath (80'C) and a warm bath (50'C).  We waited until we saw a change in the syringe weather the piston moved up or down. With the ice the piston moved down and the warm baths moved the piston up ward.

HOT BATH

ICE BATH

Our last experiment is Pressure vs Temperature this is where we had a computer out and hooked up a pressure sensor to a test tube to measure how much pressure is in the test-tube in a certain temperature. We had a hot bath (80'C) Ice bath (0'C) Warm bath (50'C). The graph below shows the pressure for the certain temperature. The colder the temperature less pressure the higher the temperature the greater the pressure.

Hot bath connected to the pressure sensor.

This is a diagram of a TV and you put your penceil in the holes. If you put it in the pressure slot it explains if that temperature and volume that if pressure goes up volume and temperature will decrease and if pressure goes down they increase. For the temperature slot if the volume goes up the pressure will decrease and if pressure goes up volume will decrease. For the volume slot if it increases the temperaute and pressure decrease and if volume decreases the temperature and pressure will increase.
