Question

motor oil would float on top of mineral oil
densities of some common liquids
liquid\tdensity (g/ml)
water\t1.0
rubbing alcohol\t0.8
corn syrup\t1.4
molasses\t1.4
honey\t1.4
motor oil\t0.9
mineral oil\t0.8
corn oil\t0.9
true
false

Explanation:

Step1: Check densities

The density of motor oil is 0.9 g/mL and the density of mineral oil is 0.8 g/mL.

Step2: Analyze floating - sinking rule

A substance with a higher density will sink in a substance with a lower density. Since 0.9>0.8, motor oil has a higher density than mineral oil. So motor oil will sink, not float.

Answer:

False
