将冰块放入液体中,冰块熔化后,液面高度如何变化?变化的情况取决于什么?下面我们通过例题来回答上面两个问题.例1一块冰浮在水面上,如图1所示,当冰块熔化后,水面______(填“下降”、“保持不变”或“上升”).解析:根据物体的漂浮条件,冰的重力等于它所受的浮力,所以F浮=G重.根 Put the ice cubes into the liquid. After the ice cubes are melted, how does the liquid height change? What does the change depend on? Here are two examples to answer the above two questions. Example 1 A piece of ice floats on the water, as shown in Figure 1. Shows that when the ice cube melts, the surface of the water is ______ (filling “falling”, “keeping it unchanged”, or “rising”). Analyze: According to the floating conditions of the object, the ice’s gravity is equal to the buoyancy it receives, so F float = G. Root
