For a perfect gas, according to Boyle’s law (where p = Absolute pressure, v = Volume and T = Absolute temperature)

A

$$\frac{{\text{v}}}{{\text{T}}}$$ = constant, if p is kept constant

B

pv = constant, if T is kept constant

C

$$\frac{{\text{T}}}{{\text{p}}}$$ = constant, if v is kept constant

D

$$\frac{{\text{p}}}{{\text{T}}}$$ = constant, if v is kept constant

If A varies directly proportional to C and B also varies directly proportional to C, which one of the following is not correct ?

A

$$\left( {A + B} \right)\alpha \,C$$

B

$$\left( {A - B} \right)\alpha \,\frac{1}{C}$$

C

$$\sqrt {AB} \,\alpha \,C$$

D

$$\frac{A}{B} = {\text{constant}}$$
