Kinetic Theory

Question 1

Force is measured in?

Answer 1

Newtons (N)

Question 2

Area is measured in?

Answer 2

m^2, cm^2 or sometimes mm^2

Question 3

Units of pressure are?

Answer 3

N/m^2, N/cm^2 or N/mm^2

Question 4

Pressure has another unit which is?

Answer 4

Pascal (Pa)

Question 5

What can pressure be thought of?

Answer 5

A concentration of a force over a surface area

Question 6

Large surface = ???

Answer 6

Less pressure

Question 7

Small surface = ???

Answer 7

A lot of pressure

Question 8

How does gas cause pressure?

Answer 8

Particles colliding with the wall of a container

Question 9

How do you convert degrees C to kelvin?

Answer 9

Add 273

Question 10

What temperature is absolute zero?

Answer 10

0 kelvin/-273 Celsius

Question 11

Describe arrangement of atoms in a:
· Solid
· Liquid
· And gas

Answer 11

Solid - vibrate
Liquid - move together
Gas - rapid random movement

Question 12

Describe forces of atoms in a:
· Solid
· Liquid
· And gas

Answer 12

Solid - strong force
Liquid - weak force
Gas - no force

Question 13

Why do single gas atoms move randomly?

Answer 13

No intermolecular forces between atoms

Question 14

How does gas produce outward pressure?

Answer 14

· Molecule colliding with wall, a change in momentum
· Produces force on wall
· Considering area of the container, a pressure is exerted

Question 15

How does pressure increase when gas compressed in smaller volume?

Answer 15

More collisions due to smaller space

Question 16

If volume of container is same, but gas heated, how is pressure increased?

Answer 16

· Atoms move faster due to increase in kinetic energy
· More collisions
· More pressure

Question 17

How does increase of mass of gas (number of atoms), increase pressure?

Answer 17

More molecules, more collisions, increased pressure

Question 18

Pressure increases, volume…?

Answer 18

Decreases

Question 19

Small pressures produce…?

Answer 19

Large volumes

Question 20

Large pressures produce…?

Answer 20

Small volumes

Question 21

Look at pages 22-27

Answer 21

Thanks bro, i really needed it, but maybe not in the situation I’m in on fucking Sunday

Question 22

Describe each process as ice cube is gently heated

5 processes, include reversal too

Answer 22

1. Solid
2. Melting (Reversal = freezing)
3. Liquid
4. Boiling (Reversal = condensing)
5. Gas

Question 23

What is kinetic energy?

Answer 23

A particle has this due to movement of the particles

Can be measured as temperature

Question 24

What is potential energy?

Answer 24

A substance has this due to bonds breaking and overcoming the molecular attractive forces

Question 25

Look at pages 30 - 33

Answer 25

I gotchu’ buddy :)

But it’s literally not needed
