chem gas laws test Flashcards
Why do you use the first and last data points and not consecutive data points when finding a value based on info from a chart
Error gets magnified when you use consecutive data points.
The margin of error is reduced with the greater range. The first and last points represent a complete set of data.
What are the different values for pressure
1 atm= 14.7 psi= 760 torr= 760 mm Hg= 101300 Pa= 101.3 kPa
What are the different values for pressure
1 ml= 1 c^3, 1000 ml= IL
