What is an element?
An element is a material of nature listed in the periodic table with a unique group of letters and they are made up of all the same atoms.
What is a conductor?
A conductor allows heat to go through it
What are objects that absorb and pass heat on quickly called?
Objects that absorb and pass on heat are called conductors
What are objects that do not absorb heat very well and take a very long time to get hot?
Items that do not absorb heat very well and take a very long time to get hot are called insulators.
Are most metals conductors or insulators?
Most metals are conductors (including lead)
What do particles do when they get hot and what does this mean for solids?
Particles vibrate when they get hot. The vibrations pass from one particle to the other. In a solid particles are closer together, meaning the heat travels faster.
When particles are given more energy (are heated) they vibrate more. What does this mean for volume and mass?
This means that they take up more volume but still have the same mass.
Which material will rise above the other; less dense or more dense
When something is less dense it rises above more dense materials.
What does a material need to be less dense?
For something to be less dense it either needs to be lighter or take up a bigger volume.
What does radiation refer to?
Radiation refers to infrared radiation {heat}
Can infrared radiation travel through a vortex? Why?
Yes, because it doesn’t need any particles to travel.
How does infrared radiation affect the earth?
The earth is heated by the sun with infrared radiation
