Question 1

Name four fossil fuels

Answer 1

Peat
Coal
Oil
Natural gas

Question 2

What is a fuel

Answer 2

A fuel is a substance that is burned to release energy

Question 3

What is the definition of finite

Answer 3

An limited source of a product

Question 4

What is combustion

Answer 4

rapid chemical combination of a substance with oxygen, involving the production of heat and light.

Question 5

Hydrocarbon + Oxygen >

Answer 5

Carbon dioxide + water

Question 6

Describe carbon monoxide

Answer 6

Carbon monoxide is an poisonous, colourless gas which stops blood from carrying oxygen

Question 7

What dose the universal indicator do when an acid has formed

Answer 7

It changes to a pinky organ he colour

Question 8

What dose burning a fossil fuels produce

Answer 8

It produces acids gasses, carbon dioxide, sulphate dioxide and other oxides of nitrogen

Question 9

What are the affects of acid rain

Answer 9

Causes serious harm to plants and animals

The damage is leaves, we can use photosynthesis

PH of rivers, increase killing fish

Causes damage to metal structures and other building stonework 

Question 10

What is the pH rainwater?

Answer 10

The pH of 5 to 6 

Question 11

Why is normal rainwater slightly acidic

Answer 11

rainwater is natural acidic due to natural occurring carbon dioxide being dissolved and rainwater. These gases are produced by burning fossil fuels lower than the pH of rainwater.

Question 12

What is biomass

Answer 12

Biomass is a material obtained from a living thing that can be burned to produce energy

Question 13

Is biomass renewable source of energy

Answer 13

Yes, because it can be made from renewable source of energy

Question 14

How is an ethanol made

Answer 14

Ethanol made by from a process that from using yeast to convert sugars then to ethanol

Question 15

Is bio ethanol cheap to produce

Answer 15

Yes because it is made from a waste product

Question 16

What are the advantages of bio ethonal

Answer 16

Advantage of bioethanol is that crops grown from bio ethanol take away carbon dioxide from the atmosphere making it good for the atmosphere

It’s is also cheep to produce and is not a finite source

Question 17

What is combustion

Answer 17

Combustion as a substance reacts with oxygen released energy

Question 18

What is an exothermic reaction

Answer 18

Exothermic reactions release heat

Question 19

What re the stages of exothermic reactions

Answer 19

moving from gas to liquid to solid

Question 20

How is coal formed

Answer 20

Coal is formed when dead plant matter crushed in swamp environments and is subjected to heat and pressure over hundreds of millions of years

Question 21

How is oil formed

Answer 21

Oil is formed from the fossilised remains of small marine life, such as plankton, that died and fell to the bottom of the sea. Their remains were then covered by mud and dirt which began to turn to rock as heat and pressure increased over time

Question 22

How is natural gas formed

Answer 22

formed from the remains of ancient animals and plants that were buried & compressed for millions of years

Question 23

How is Piet formed

Answer 23

Peat is a type of soil made of dead plants that have not completely rotted

Question 24

What happens in incomplete combustion

Answer 24

Carbon (soot) and carbon monoxide are produce

Question 25

How do we get oil out of the ground

Answer 25

Fracking

Question 26

What is incomplete combustion

Answer 26

An limited supply of oxygen hydrocarbons burn incompleatly leaving soot
