Apiece of metal with a mass of 159 g is placed in a 50 ml graduated cylinder. the water level rises from 20. ml to 41 ml. what is the density of the metal?

Volume of water displaced is equal to the volume of the metal. So 41 - 20 = 21 ml. Density = mass / volume so density = 159 / 21 = 7.57 g/ml

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
