The work done to submerge the ice block is W = V ice x ρ ice / ρ water
Explanation:
A block of ice whose area =A
Height=h=h
Water density =ρo
Work done =?=?
Density of ice ρ1
Work = ρ ice / ρ water ×V ice
Wρ w = ρ ice × V ice
V mass of the ice = V water ×ρ water (mass)
W = V ice x ρ ice / ρ water
Hence the work done to submerge the ice block is W = V ice x ρ ice / ρ water
