Answer:
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
A solid object will float on a liquid if the solid is less dense than the liquid.
We don’t often think about this, but ice floats on liquid water, because ice is less dense than water. It is one of the few substances whose solid is less dense than its liquid. If it weren’t, ice would drop to the bottom of the oceans and lakes, and these bodies of water would remain frozen year round. Life would almost certainly not have evolved on Earth if this were the case.
