For 1 mol of an ideal gas at a constant temperature T, the plot of (log P) against (log V) is a(P: Pressure, V\ Volume)   JEE Main Online Paper (Held On 07 May 2012)

A) Straight line parallel to x-axis.

B)                        Straight line with a negative slope.

C)                        Curve starting at origin.

D)                        Straight line passing through origin.

Correct Answer: B

Solution :

                According to Boyle's law, PV= constant \[\therefore \]\[\log P+\log V=\] constant \[\log P=-\log V+\]constant Hence, the plot of log Pvs log V isstraight line with negative slope.
