If a barometer were built using ethanol () instead of mercury would the column of ethanol be higher than, lower than, or the same as the column of mercury at 1.00 atm?

The column of ethanol will be higher than the column of mercury.

Explanation:

The pressure (P) of a column of liquid can be calculated using the following expression.

P = ρ . g . h

where,

ρ: density of the liquid

g: gravity

h: height of the column

h = P / ρ . g

We can see that the height of the column is inversely proportional to the density of the liquid. The density of ethanol (0.789 g/mL) is lower than the density of mercury (13.6 g/mL). Then, under the same conditions, the column of ethanol will be higher than the column of mercury.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
