Answer :
wood sinks in ethanol => wood has higher density than ethanol.
wood floats in gasoline=> wood has lower density than gasoline
wood floats in gasoline=> wood has lower density than gasoline
Answer: gasoline has more density than wood and wood has more density than gasoline.
Explanation:
Density is defined as the mass contained per unit volume.
[tex]\text{Density of substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}[/tex]
A substance having more density will sink at the bottom and the substance having less density will float at the top.
As the wood sinks in ethanol , it means wood has more density than ethanol.
As the wood floats in gasoline, it means wood has less density than gasoline.
Hence, the order of density will be gasoline > wood > ethanol.
