Ineed really quick right now! answer this quetion plz: a solid is cooled to a very low temperature. assuming the mass remains constant, how, if at all, does this affect the density of the solid? enter your answer in the space provided.

most solids contract (shrink) when they get cold.

        Density  =  (mass) / (volume)

If mass doesn't change but volume gets smaller,  then density increases.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
