What are the 2 questions that we ask to determine a materials state of matter?
1. Does it have a definite shape?
2. Does it have a definite volume?
If an object is 60kg on Earth- is that it's mass or it's weight? why?
kg = mass
True or false: the density of an object changes if the amount of the sample changes.
FALSEEEE
"amount of sample" = volume
Why do solids have a definite shape and volume?
because their particles stay in a definite location and vibrate.
