What Is the Conductivity of Ethanol?

Ethanol’s thermal (heat) conductivity is 0.171 W/m K at 300K at a temperature of 25 degrees Celsius. Ethanol’s electrical conductivity is zero, because it does not contain any electrolytes, which are required for electricity to flow through a liquid.

Ethanol is known as an alternative fuel, but ethanol by itself cannot power a car. However, when ethanol is mixed with gasoline, the resulting liquid is able to carry enough energy to power a vehicle. To promote the use of renewable fuels, the United States government requires the addition of at least 10% ethanol to gasoline. Ethanol fuel blends are available from E10 to E85 with the numbers indicating the percentage of ethanol on the solution.
