Ice
Table
Expansion and contraction
Expansion
When an object gains heat, it
EXPANDS
When an object expands, its volume increases but its mass stays the same
Contraction
When an object loses heat, it
contracts
When an object contracts, its volume decreases but its mass stays the same
Is heat the same as temperature?
Ans: No!
Heat is a form of energy
Temperature is a measure of how hot something is
Conductors ------ Good and Bad?
Ans: No!
Not
Bad
conductors, it's

A poor conductor does not allow heat to flow through easily
Examples
Good conductors
Water/Alcohol
Metal
Diamonds
Bad conductors
Air
Clay
Stone
Heat flow
Heat flows from hot to a lack of heat until they meet the same temperature
How does the temperature or volume of item affect the amount of heat in an object?
