What is a cooling curve?
100
This is a state of matter in which the material has a definite volume, but not a definite shape (fits the shape of the container)

300
Iron rusting is this type of change
What is chemical (a new substance is formed)?
300
This is the phase change occurring at 4
What is vaporization?
300
This phase of matter retains its shape and volume and has the strongest attractive forces

500
This is the difference between a physical and chemical property
What is a chemical property will involve a material's ability to form new substance , while a physical property is used to identify a substance without changing its composition?
500
These are three signs of a chemical change:
What is
a) change in color
b) formation of a gas
c) formation of a precipitate
d) change in odor
e) change in heat or light
