Equation for Boyle's law is

Options

A. `(dp)/(p) = -(dV)/(V)`
B. `(dp)/(p) = +(dV)/(V)`
C. `(d^(2)p)/(p) = - (dV)/(dT)`
D. `(d^(2)p)/(p) = + (d^(2)V)/(dT)`

Answer

A

Explanation

According to Boyle's law,
`pV = constant (k) (n , T constant)`
Differentating both sides , we get
`pdV + Vdp = 0`
or `Vdp = -pdV`
or `(dp)/(p) = -(dV)/(V)`
