✔ 最佳答案
要知物件能否浮於水面, 要計算它的密度密度的定義為 重量/體積
水的密度為 1, 密度小於1的東西就可浮於水
水星的平均密度為 5.4
金星的平均密度為 5.2
地球的平均密度為 5.5
火星的平均密度為 3.9
木星的平均密度為 1.3
土星的平均密度為 0.7
天王星的平均密度為 1.3
海王星的平均密度為 1.6
冥王星的平均密度為 2.1
由此得知, 土星是會浮於水面

Saturn,because it's density is only 0.69.Saturn is 95 times larger than Earth.However,
Saturn is less dense than water,so if it was placed in water it would float.Saturn is made
of gases just like Jupiter and a raging storm spreads across the planet every 30 years.

土星。
因為質量輕。
