The density of a substance___________as the temperature increases.
I believe the answer is 42.
are you sure, i dont think so!!! im not sure if its increases or decreases
When temperature increases what happens to mass? What happens to size?
Stuff gets heavier when heated or size gets larger when heated?
Size gets larger when heated
What about mass?
Mass represents the amount of matter you have.
Changing the temperature won't change that amount.
If the density increases the (fixed mass) of substance contracts, right? If density decreases...
Put like that you probably know a rule, backed up by some direct experience.
But it is a rule with important exceptions.
Separate names with a comma.
