Experiment 6: Gas Laws 1- Boyles and Charles

Question 1

Boyles Law

Answer 1

PV=PV=constant. Pressure is proportional to the inverse of volume

Question 2

A Plot of P vs. V would give a….

Answer 2

Hyperbola that rides y axis, then pulls away at the origin, then rides x axis

Question 3

A plot of P vs. 1/v would give….

Answer 3

A line y=x

Question 4

Charles Law

Answer 4

V/T=V/T=constant Volume is proportional to temperature

Question 5

Temp (c) vs volume…

Answer 5

Y=x-273, absolute zero

Question 6

Procedure:

Answer 6

1) Set syring to 25 ml+5ml tubing=30ml

2) Vary volume (10-65), record pressure

Question 7

Assumption: temp is constant. True/False?

Answer 7

False, as pressure increases temperature increases and vice versa. We both compressed and expanded though so its negligible!

Question 8

Assumption: Pressure is constant. True/False?

Answer 8

Mostly, as the glycerin plug moves there is friction. This is reduced by priming the pipet.

Question 9

Read the pipet with the tip being __ml.

Answer 9

0.0 mL

Question 10

760 torr = ? mmHG = ? atm = ? mmH2O

Answer 10

760 mmHg
1 atm
13.6 mmH2O

Question 11

The correlation coefficient should be what to indicate a good correlation?

Answer 11

Close to 1
