A peice of ice , with a stone frozen inside it, is floating in water contained in beaker. When the ice melts, the level of water in the beaker ? Give reason if possible.
the level of water will decrease..when the ice is floating then weight of ice and stone = upthrust...let the mass of stone and ice be m1 and m2..thus (m1+m2)g=v(immersed)(density of water)g hence v(immersed)= (m1+m2)/desity of water.volume of water from mass m1 of ice=m1/desity of water.. volume of stone(volume of water displaced)=m2/density of solid..since density of solid> density of water..hence v1+v2
