Question

If the pressure is `0.7*atm`, what length of mercury column will this pressure support?

Answer 1

Approx. `532*mm*Hg..........`

Explanation:

`"One atmosphere"` will support a column of mercury that is `760*mm*Hg`..........And thus a column of mercury is a good visual measure of the pressure of a quantity of gas.......

And so `0.7*cancel(atm)xx760*mm*Hg*cancel(atm^-1)=??*mm*Hg.`
