Question

There is a leak proof cylinder of length 1 m , made of a metal that has very low coefficient of expansion is floating vertically in water at 0 ° C such that its height above the water surface is 20 cm . If the temperature of water is increased to 4 ° C , the height of the cylinder above the water surface becomes 21 cm . The density of water at T = 4 ° C , relative to the density at T = 0 ° C is approximately, 1 . 03, 1 . 04, 1 . 26, 1 . 01
