Question

A solid body of linear expansion coefficient 1 0 − 5 / ∘ C , floats in a liquid with 40% of its volume out of the liquid at a temperature 0 ∘ C . The volumetric expansion coefficient of liquid is 2 times of the solid body. If the temperature is increased to 100°C, the new fraction of the body's volume out of liquid will be about
