Question

find out density of ethanol describe​

Answer 1

Answer:

It is measured in g/cm3. In the case ofethanol, the density is 0.789g/cm3 at a temperature of 20°C, which is the accepted density. It will vary as temperature goes down or up. The higher the density of ethanol, the more heat it will produce.

Answer 2

Answer:

Explanation:

--> Density is by definition the mass per unit of volume.

--> The density of ethanol will depend on the temperature and pressure of surroundings.

--> Alterations in these factors result in change in the volume of the liquid, which in turn results in change in density. When an object floats on water, it density is smaller than the density of water. If it sinks, then its density is higher. It is measured in g/cm³.

--> In the case of ethanol, the density is 0.789g/cm³ at a temperature of 20°C, which is the accepted density. It will vary as temperature goes down or up. The higher the density of ethanol, the more heat it will produce. As a polar solvent ethanol can subdue the hydrocarbon emissions generated by burning gasoline, hence the environmental advantage of flex fuel vehicles.
