天津市２００１年中考试题第３４题：一个内部含有石块的冰块放在密度为ρ０＝０．９５×１０３kg／m３的液体中恰好能悬浮。一个底面积为S＝１００cm２的圆柱形容器中装有水，将这个含有石块的冰块放入水中后，容器中的水面较原来升高了h１＝２．０９cm。待冰熔化后，水面又下
Tianjin Middle School 2001 Test Question 34: An ice cube with internal stones is just suspended in a liquid with a density of ρ0 = 0.95 × 103 kg/m3. A cylindrical container with a bottom area of S=100 cm2 was filled with water. After placing this cube containing ice into the water, the water level in the container was increased by h1 = 2.09 cm. After the ice melts, the water surface goes down again
