Question

Which is the true graphical representation of V vs 1/p.

Answer 1

The true graphical representation of

V vs 1/P is a straight line, not passing through origin.

(Refer to the image attached below)

• Here, V reprsents volume of the gas, and P represents pressure of the gas.

• According to Boyle's law, at a constant temperautre,

PV = k (constant)

=> V = k × (1 / P)

=> V ∝ 1 / P

• Therefore, volume is inversely proportional to pressure.

• In other words, if pressure on a gas increases, its volume decreases. If pressure on a gas decreases, its volume increases.

• Therefore, it can also be said that volume is directly proportional to the inverse of pressure.

• Volume and pressure of a gas can never be zero.

• Hence, the graph of V vs 1/P is a straight line, not passing through origin.
