Questions:

1.	What happened to the molecules when you changed the temperature? 
The higher the temperature the faster the molecules moved, However, the lower the temperature the slower the molecules moved. 

2.	Describe the movement of the molecules when you changed the pressure.   The higher the pressure level of the molecules the faster they move. 

3. 	What is the relationship between volume and temperature? How do you know this? Volume and temperature have a steady about one to one ratio, as the temperature raises so does the volume. 
 
4.	What is the relationship between volume and pressure? How do you know this?  The volume and pressure reveal the amount of space the molecules have to move.  You can make this conjecture because they are represented together in the lab.  Meaning that they occupy the same space. 
 
5.	What is the relationship between volume and number of molecules? How do you know this? As the molecules increase so does the volume.  This can be determined by the upward trend in the scatter plot.  
 
6. 	What happens to the molecules of the gas when the temperature is zero? Why?  When the molecules of gas have a volume of zero  and a temperature of zero, they are no longer active.  The extreme low temperature is the cause for this reaction of the molecules.  They need space and temperature to become active.
