chem h gas notes

Question 0

Kinetic molecular theory

Answer 0

Gases have mass
Gas Particles are widely spread apart
Gas particles are in in constant rapid motion
Gas particle exert pressure BC they collide with walls of container
Average kinetic energy depend on temperature
Gases particles aren’t attracted or repelled

Question 1

Physical properties so gases

Answer 1

Have mass, easily compressed, expand to fill their container, can travel through each other, exert pressure

Question 2

4 Variables of gas

Answer 2

1. Amount (moles/n)
2. volumed (L/v)
3. Temperature (Celsius/kelvin)
4. Pressure

Question 3

Atmospheric pressure

Answer 3

Pressure exerted by the weight of the air in the atmosphere

Question 4

1 atm

Answer 4

101,325 Pa
760 mm Hg
760 torr
14.70 lb/in2
101.325 kPa

Question 5

Pressure changes with

Answer 5

Altitude and weather

Question 6

Top tube of a barometer

Answer 6

Vacuum

Question 7

How a barometer works

Answer 7

Mercury in the column will go down until the pressure from the atmosphere equals the pressure in that column

Question 8

Manometer

Answer 8

Bulb containing a gas and u shaped tube

Question 9

Boyce’s law

Answer 9

states that volume and pressure are indirectly proportional when temperature and amount are held constant

Question 10

Boyle’s law formula

Answer 10

P1V1=P2V2

Question 11

Charles’ Law

Answer 11

States that volume and temperature are directly proportional when pressure and amount of gas are held constant

Question 12

In order to keep pressure the same when increasing temp. You must increase

Answer 12

Volume

Question 13

Directly proportional

Answer 13

As one variable increases so does the other

Question 14

Charles’ Law Formula

Answer 14

V1/T1=V2/T2

Question 15

Dalton’s Law of Partial Pressures

Answer 15

The sum of all partial pressures is equal to the total gas mixture pressure

Question 16

Dalton’s Law of Partial Pressures Formula

Answer 16

PT=p1+p2+p3…
