When a cube is placed in water at

4^{\circ} \mathrm{C}

, the fraction of volume of it submerged in water is '

x

'. When the temperature of water is

20^{\circ} \mathrm{C}

the fraction of volume of it submerged in water becomes '

y

'. If the volume of the cube does not change with temperature then

View answer and explanation

Correct option: B

y > x

Option B (

y > x

) is correct because the density of water is maximum at 4°C, so the fraction submerged will be smaller at 4°C than at 20°C.
