Worked Solution & Example Answer:Ice floats on water but ice sinks in ethanol (an alcohol) - Junior Cycle Science - Question b - 2007

Step 1

(i) the density of water

96%

114 rated

Answer

Ice floats on water, which indicates that the density of ice is less than that of water. This is because when an object is less dense than the liquid it is placed in, it will float. Hence, we conclude:

The density of ice is less than the density of water.

Step 2

(ii) the density of ethanol

Answer

Ice sinks in ethanol, which suggests that its density is greater than that of ethanol. In this case, when an object is denser than the liquid, it will sink. Therefore, we can conclude:

The density of ice is more than the density of ethanol.
