Who do Thermometers work |
Thermometers measure how fast the atoms and molecules are moving on average |
|
|
Where do Thermoeters mainly work |
Mainly by conduction |
|
|
When a substance absorbs heat what will happen |
It will expand |
|
|
What is this called |
thermal Expansion |
|
|
what is expansion |
when a substance takes up more volume |
|
|
What is the opposite of expansition |
Contraction |
|
|
When douse something contarct |
most substance contract when they lose heat |
|
|
What is an exception for expantion |
Water |
|
|
What happens at 4c |
The molecules start to expand again |
|
|
Diaphragm from a water and density |
Ok |
|
|
What takes up more space |
Solid then gas then liquid |
|
|
When is ice less dense |
Between freezing and boiling point |
|
|
what happens when water freezes in a pipe |
it will expand with a lot of force |
|
|
what would happen to the lake if water would contiued to be more dense |
The lake wouled turn into solied and then ice wouldnt flow any more and then all animals are dead |
|
|

a conductor for example metal |
|
|
What is a material called that conductes heat porrly Example |
Insulator wood plastic |
|
|
General propoties of metal |
conduct electricity conduct heat hard high melting point shiney maleable can be bend with out breaking Ductile an be streched with out breaking |
|
|
General properties of non metal |
poor conductor of heat poor conductor of electricity low melting point brittel can break dull |
|
|
