Question

PLEASE HELP! When an object is cooled down, it's density will _____; its mass will _____; its volume will____.

Answer 1

at constant pressure....
we got that temperature and volume are directly related, so if one goes up the other will too.
then..in this case the temperature is going down , so the volume will be decreased.

The density will raise, because Density= mass/ volumen.

And it's mass will be the same, because you are not adding o extracting nothing.
