Which of the following ratios express pressure?

Options

A. Force/Area
B. Energy/Volume
C. Energy/Area
D. Force/Volume

Answer

A, B

Explanation

Pressure `=("Force")/("Area")`
[Pressure] `=[MLT^(-2)]= [ML^(2)T^(-2)]`
Now, `("Energy")/("Volume")=("Force")/("Area" xx "Distance")= ([ML^(2)T^(-2)][L])/([L^2][L])`
`=[ML^(-1)T^(-2)]`
= [Pressure].
