Gas Laws

Question 1

Gas Pressure

Answer 1

-P
-Caused by # of Wall collisions
-1 atm=101.3 kpa=760mmHg=14.696ib/in2

Question 2

Gas Temp

Answer 2

• ^T, ^KE/motion
  -No motion at absolute zero

MUST BE KELVIN
K=c+273

Question 3

Gas V

Answer 3

V=Space a gas takes up
1mol= 22.4L at STP

Question 4

Gas particles

Answer 4

Particles=n(moles)

Question 5

Kinetic Theory of Gases

Answer 5

1. Tiny particles in constant random motion
2. particles far apart (volume&space)
3. NOT repel/attract, NO IMFS
4. Wall collisions, no loss in energy
5. Avg. Kinetic energy directly proportional to kelvin temp scale.

Question 6

Directly proportional meaning

Answer 6

Increase and decrease together

Question 7

Boyle’s Law

Answer 7

-T is Constant
VP=VP
Inversely Proportional poopy

Question 8

Inversely Proportional

Answer 8

As one of the values increases, the other decreases.

Question 9

Charles’s law

Answer 9

P is Constant
V/T=V/T
Directly Proportional
when a balloon is heated, the air inside expands and the balloon inflates

Question 10

Gay-Lussacs’ Law

Answer 10

V-constant
P/T=P/T
Directly Proportional

Question 11

Combined Gas Law

Answer 11

ALL 3 change
NO CONSTANT
VP/T=VP/T
T-Kelvin

Question 12

Ideal Gas Law

Answer 12

PV=nRT

P= atm
V= L
n=#of mols
T=kelvin

Question 13

R

Answer 13

Gas Constant
0.0821 L.atm/mol.k

Question 14

Absolute Zero

Answer 14

0k
lowest energy
NO moment (only vibrating)

Question 15

STP

Answer 15

Standard Temperature and Pressure.
Standard temp.: 273 K
Standard pressure: 1 atm

Question 16

Density

Answer 16

Mass/volume
g/L

Question 17

Density/Molar Mass

Answer 17

D= PM/RT
