Question

An ice cube floats on water but it sinks in alcohol because

Answer 1

an ice cube floats on water bcoz it has more density in water but it sinks in alcohol bcoz alcohols density is much greater than an ice cube
...hope this may helps you....

Answer 2

Because the density of ice is higher, at least for ethanol alcohol. The density of ice is 0.917 grams per cubic centimeter, that of water is 1. So ice, being less dense than water will float. The density of ethanol alcohol is 0.789 so ice will sink in it.
