Fossil Fuels Flashcards
What are all the types of energy
Electrical Energy, Kinetic Energy, Sound Energy, Light Energy, Heat Energy, Gravitational Potential Energy, Chemical Potential Energy, Elastic Potential Energy, Nuclear Energy
What Energy did the Māori use
Wind and Wave power for the Wakas, Fire for Food, Coal burnt by Iwi in the central north island
What are types of fossil fuel
Solid, Liquid, Gas
What are types of fossil fuel
Solid, Liquid, Gas
How was oil and gas fossil fuels formed
Dead animals were squashed beneath the ground and unable to rot due to the lack of oxygen which over millions of years they were squashed enough until they formed oil and gas
How was coal fossil fuels formed
Dead plants were squashed under swamps and unable to rot due to the lack of oxygen so over millions of years they formed a solid fuel called coal
Why are fossil fuels so important
Our worlds economy and infrastructure have been designed by the use of fossil fuels such as farming, transport, and electricity
Uses of fossil fuels
Provides electricity, Heat, Transportation, Manufacturing medicine

Copper atoms
What is carbon element made of
Carbon atoms
What is helium element made of
Helium atoms
What are atoms
Basic building blocks of matter
What are elements
Anything on the periodic table
What does the atomic number stand for
The Number on the top stands for the number of of protons/electrons found in the nucleus
What does the mass number stand for
The number on the bottom stands for the total number of protons and neutrons in the nucleus
What particles is a atom made of
Electrons, Protons, neutrons
Are protons negatively or positively charged
Positively
Are Electrons positively or negatively charged
Negatively
How do i find the Mass number in a element
Number of protons + number or neutrons
How do i find the number of neutrons in a element
Mass number - atomic number
What is Magnetism
Separates magnetic material from non magnetic
What is distillation
Separates Liquids with different boiling points
What is chromatography
Separates liquids of different colours
What is filtration
Separates insoluble solid from a liquid
What is evaporation
Separates a soluble solid by boiling off
What are elements made up of
Only one type of atom which as iron (Fe)
What are elements made up of
Only one type of atom which as iron (Fe)
What are compounds made up of
compounds are made when two or more different elements chemically combine for example water (H20) carbon dioxide (CO2)
Are elements a pure substance
Yes
Are compounds a pure substance
Yes
Are mixtures a pure substance
No
What are mixtures made of
Mixtures are made of more than one substance compound or element and they are not bonded together for example (sea water, the air, alloys and oil)
What’s the difference between a pure substance and a mixture
Pure substances have particles which are all the same and mixtures contain different particles
