INTERMOLECULAR FORCES LAB

Gas Behavior

In the gas behavior lab we had three different lab the first one Temperature vs. Volume, Volume vs. Pressure, and Pressure vs. Temperature.

All of these have there own law. 

Boyle's Law- Is when pressure is up, volume is down.

Guy- Lussac's Law- Temperature is up, pressure will be up. 

Charle's Law- Volume is up, temperature up.

This lab we did Temperature vs. Volume. We used a test tube that was hooked up to a temperature probe. We started the syringe at 10cc. Then we placed it in a ice cold cooler. The temperature of it was zero degrees Celsius. We watch as the syringe's piston moved in this case it move down a degree. After that we waited till the syringe got back to room temperature. Then we put it in a hot water tube, this was eighty degrees Celsius. The hot water made the syringe piston move up to 15cc. Finally we put the syringe in warm water, it was about fifty degrees Celsius. And the piston move up one degree.  

After the first lab we did Volume vs. Pressure. Here we had fun with our chemistry books.We used a piston of a syringe like in the picture below. We would stack the books on to the top of the piston to see how pressure would affect the volume. We got up to six books. Every time we would stack a book the piston would lower more and more.   

The final lab we did was Pressure vs. Temperature. For this we used a computer, pressure sensor, and  a test tube. We place the test tube into the hot bath which was 80'C and then to a ice bath 0'C. After those we places it into a Warm bath which was 50'C. This graph shows you how temperature affect the pressure of it.
