Energy Flashcards
Why are metals good conductors
It has a crystal lattus structure
What is the charge carrier in the atom
Electron
what is positive attracted to
Negative
What charge are atoms
Atoms are neutral so if you take away a proton it becomes negative, if you take away a neutron, it becomes positive.
What is insulation
Isulation is the process of keeping heat/sound/electricity from spreading
What is conduction
Conduction is when heat transfers from a hotter object to a cooler one by making contact
What is convection
Is when heat flows through liquids or gases, convection also causes heat to rise
What is radiation
Radiation is the wave of heat between objects that are not in contact with each other.

What does heat do from any hot object
Heat spreads outwards from any hot object
Why do 2 protons repel each other
Because they have the same charge, anything that has the same charge repels itself.
What is Kinetic energy
The energy of movement
What is heat energy
Is the energy of heat, it can can come from the sun, chemical reactions or people. It burns melts and dries objects.
What is sound energy
This is the energy air has when it vibrates, your brain and ears then interpret them as sounds.
What is GPE
Represents the potential energy that an object has to do work.
What is EPE
Stands for energy stored as a result of applying force to an elastic object.
How many types of atoms are elements made from
1
What are some characteristics that metals have
Lustrous, solid at room temperature, good conductors of heat and electricity, malleable, ductile
What does lustrous mean
Shiny
What does ductile mean
Can be stretched into wires
What does malleable mean
Can be bent and hammered into sheet form
What are the characteristics of non metals
Dull, not conductive and brittle
What does brittle mean
Can break or crumble when bent
What are 4 ways to save energy
Efficient housing, reducing energy consumption, insulation and innovative design.
What type of charge are protons
positive
What type of charge are neutrons
no charge
What type of charge are electrons
negative
