At a temperature t = 50°C, a solid body floats in a liquid, completely immersing itself in it. What part d of the volume of the body will be immersed in the liquid when it is cooled to a temperature t0 = 0°C, if the coefficient of volumetric expansion of the solid body bsol = 0.3 10-5 K-1, liquid bl = 8.0 10-5 K -1?
