The density of an object is 0.825 g/cm3. in which of the following materials will it not float? water, density = 1.00 g/cm3 olive oil, density = 0.920 g/cm3 ethyl alcohol, density = 0.789 g/cm3 citric acid, density = 1.660 g/cm3

The correct option is ethyl alcohol which has a density of

Explanation: There is an important role of density to determine whether a substance will float or sink.

The substance will sink, when its density is more than the density of liquid in which it is placed.

And the substance will float, if it is placed in the liquid having more density than its own.

Density of object =

And we are asked in which liquid will it not float, hence the liquid having lower density than the object will make the object sink.

Hence, the correct option is ethyl alcohol having density
