A piece of wood sinks in ethanol but floats in gasoline. Give a range of possible densities for the wood?
shouldn't you be the one telling me that.?
You can Google gasoline density and ethanol density to find that information. We don't give answers that we believe the students can readily find for themselves.
After you find the densities of gasoline and ethanol, then post them, and BobPursley or another teacher will help you then.
Maybe it would help to change gasoline to like units .737g/cm3
Now one can determine the range of densities the wood is in.
By the way, you can have the Google calculator convert units for you to CHECK your work.
Put this in the Google search window:
737kg/m^3 in g/cm^3
thats disrespectful get out if you dont have anything nice to say
To determine the range of possible densities for the wood, we need to understand the concept of buoyancy.
Buoyancy is the upward force exerted on an object submerged in a fluid (liquid or gas). This force is equal to the weight of the fluid displaced by the object. When an object is less dense than the fluid it is placed in, it floats, and when it is more dense, it sinks.
In this case, the wood sinks in ethanol but floats in gasoline. Since ethanol has a lower density than gasoline, we can conclude that the wood has a density higher than ethanol but lower than gasoline.
To find the range of possible densities for the wood, we need to compare the densities of ethanol and gasoline. The density of ethanol is approximately 0.789 g/mL, while the density of gasoline varies but is typically around 0.7 to 0.8 g/mL.
Therefore, the range of possible densities for the wood would be greater than 0.789 g/mL (density of ethanol) and less than 0.8 g/mL (upper range for the density of gasoline).
In summary, the wood in question has a density higher than ethanol (0.789 g/mL) but lower than the upper range for gasoline (0.8 g/mL).
what is the density of gasoline, and of ethanol.
Gasoline: 737.22 kg/m3
Ethanol: 0.789 g/cm³
