Question

the density of ice is 917 kg/m3. what fraction of the volume of ice will be above the water when the ice is floating in water?

Answer 1

Given,

Density of ice =917kg/m³

To Find,

Fraction of the volume of ice.

Solution,

We know, density of ice = 917 kg/ m³

Also density of fresh water = 1000 kg/m³

Lets assume v is volume of ice above water and V be total volume.

Then volume displaced in water= V-v,

By using law of floatation,

V×917×g = (V-v) ×1000×g

⇒V-v/V=917/1000

⇒1-v/V=917/1000

⇒v/V=1-917/1000

⇒v/V=83/1000

=0.083

Hence, fractional value is 0.083.
