Ametal having a mass of 44 grams is dropped in 118.2 cm3
of water and sinks to the bottom. the volume
of the water and object is 124.3 cm3
. what is the density of the metal?

The volume of the lump that was dropped into the water is

(124.3 - 118.2) = 6.1 cm³

The density of the lump is (mass)/(volume) = 44 / 6.1 = 7.21 gm per cm³.

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
