Question

You have 50L of water, it froze. So find its new volume. Density of water is 1000kg/m^3 or 1kg/L, density of ice is 920kg/m^3 or 0.92kg/L.

Answer 1

D (density) = Mass / Volume

V (ice) = Mass / Density = 50000 g / .92 kg / L

V = 50 kg / .92 kg / L

1 Liter of water weighs 1 kilogram = 50 L weighs 50000 g

V = 54.3 L the mass does not change upon the change of phase (freezing)
