The density of a substance_______as the temperature increases.

AI Thread Summary
The discussion centers on the relationship between temperature and the density of a substance. Participants debate whether density increases or decreases as temperature rises, with some asserting that mass remains constant while volume expands. It is clarified that while mass does not change with temperature, the density can decrease if the volume increases significantly. The conversation highlights that there are exceptions to general rules regarding density and temperature. Understanding these principles is essential for grasping the behavior of substances under varying thermal conditions.

are you sure, i don't think so! I am not sure if its increases or decreases
 
When temperature increases what happens to mass? What happens to size?

increases :confused:
 
Stuff gets heavier when heated or size gets larger when heated?

Size gets larger when heated
 
What about mass?

No.
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.
