C125 REVISION EXAM QUESTIONS WITH COMPETE SOLUTIONS 
 
In the molar mass lab, why was it important to level the water in the graduated cylinder with that in the through? - Answer- so that the pressure inside the cylinder would equal atmospheric pressure 
 
butane hazards - Answer- butane lighter fluid is extremely flammable. it is a mixture of two isomers both of which boil at temperatures below 0°C at 1 atm pressure. the gas is stored as a liquid in the pressurized container. However, when th...

independent variable - Answer- the quantity you vary or control; it is assigned to the abscissa (x-axis) 
 
dependent variable - Answer- the quantity you measure in the lab; it is assigned to the ordinate (y-axis) 
 
ordinate - Answer- y-axis 
 
abscissa - Answer- x-axis 
 
slope - Answer- change in y/change in x 
 
best-fit line equations - Answer- y=mx+b *m is the slope; b is the y-intercept 
 
interpolated results - Answer- lie within the range of measured data

rearrange the ideal gas equation, PV=nRT to the form y=mx+b for the case where V is plotted on the y-axis and n on the x-axis. Name the equation, slope,a dn intercept - Answer- V= RT/P (n) 
 
slope: RT/P 
 
intercept: none 
 
Interpolation - Answer- estimating a value within the range of measured data 
 
extrapolation - Answer- projection; conjecture; V. extrapolate: infer (unknown information) from known information 
 
best fit line equation commonly takes y=mx+b format. What are your y, x, and...

Interpolation - Answer- estimating a value within the range of measured data 
 
extrapolation - Answer- projection; conjecture; V. extrapolate: infer (unknown information) from known information 
 
best fit line equation commonly takes y=mx+b format. What are your y, x, and b? - Answer- y = dependent variable (v) 
x = independent (n) 
m = slope (RT/P) 
b = intercept 
 
In assignment 2 (excel), students are asked to obtain the slope and intercept by rearranging the Ideal Gas Equation into y=mx+b ...
