Kinetic Particle Theory

Question 1

Sublimation

Answer 1

The process by which a solid changes directly into a gas without going through the liquid state.

Question 2

Factors affecting rate of diffusion

Answer 2

1) temperature
2) molecular mass
3) concentration gradient
4) thickness of barrier

Question 3

Drying of gases using

Answer 3

1) concentrated sulfuric acid
2) quicklime (calcium oxide)
3) fused calcium chloride

Question 4

Using concentrated sulfuric acid

Answer 4

Can dry most gases except ammonia

Question 5

Using calcium oxide

Answer 5

Can be used to dry ammonia gas, not used to dry acidic gases

Question 6

Using fused calcium chloride

Answer 6

Dry most gases except ammonia

Question 7

Deline Kinetic Particle Theory

Answer 7

States that all matter is made up of tiny particles that are in constant, random motion.

Question 8

Gases that use upward delivery

Answer 8

Ammonia

Question 9

Gases that use downward delivery

Answer 9

Hydrogen chloride
Chlorine
Sulfur dioxide

Question 10

Gases that use delivery over water

Answer 10

Oxygen
Hydrogen
Carbon dioxide
Methane

Question 11

Evaporation

Answer 11

Process by which a liquid changes to a gas at temperatures lower than the boiling point.

Question 12

Condensation

Answer 12

The process by which a gas changes to liquid. It happens when hot vapour touches a cooler surface.
