Hey, everyone~
How did you do on Lab 2E Quiz today??
It was basically a complete summary of out Lab 2E: Determining Aluminum Foil Thickness.
Some of the important formulas were tested:
1. Volume = Length x Width x Height (thickness)
2. Density = Mass / Volume.
3. Mass = Density x Volume
4. Volume = Mass / Density
5. Percentage of Error = (your measurement -accepted measurement) / accepted measurement x 100%
* Also remember the answer should be positive!
I believe these will be important for the Chapter 3 test coming up too!
We also learned graphing skills on EXCEL in the computer lab...
By using EXCEL, we observed the relationship between X and Y more clearly and find the slope and equation. The slope = the Density when X is Volume and Y is Mass.
In the case of the example we did today: Temperature Vs. Density, we had to answer the question why is hot water more dense than cold water?
