A solid floats in a liquid at 20 °C with 75% of its volume immersed in the liquid. When the liquid is heated to t °C , 80% of volume of the solid is immersed in the liquid. If the absolute expansion of the liquid is 8.33 x 10−4°C−1 then the temperature t is approximately (Expansion of solid is negligible)
