The density of an object is 800 kg/m^3. In which of the following will it float?
AWater (1000 kg/m^3)
BAlcohol (790 kg/m^3)
CPetrol (700 kg/m^3)
DNone of these
✓ Correct Answer: A — Water (1000 kg/m^3)
An object floats if its density is less than the density of the liquid. 800 < 1000, so it floats in water.
