## anonymous one year ago 6. The density of a certain liquid is given an equation of the following form: D= (A + B t) e^(C)(P) Where D= density in g/cm3 t = temperature in oC P = pressure in atm If the equation is dimensionally consistent, What are the units of A, B and C ?

1. Michele_Laino

is your equation like this: $\Large P = \left( {A + Bt} \right){e^{CP}}$

yes :)

if yes, then A has the dimension of a "density", whereas B has the dimension of "density/temperature" C*P has to be a number, so C has the dimension of "pressure^(-1)" or (1/pressure)

i got it, thank you @Michele_Laino :)
