उत्तर

a and c

Explanation:

For ideal gas behaviour,

PV = nRT ......(i)

(a) When pressure, P = constant

From (i) Volume V ∝ Temperature T

The graph of V versus T will be a straight line.

(b) When T = constant

From (i) PV = constant

So, the graph of P versus V will be a rectangular hyperbola. Hence this graph is wrong. The correct graph is shown below:

(c) When V = constant

From (i) P ∝ T

So, the graph is a straight line passing through the origin.

(d) From (i) PV ∝ T

⇒ `(PV)/T` = constant

So, the graph of PV versus T will be a straight line parallel to the temperature axis (x-axis).

i.e., the slope of this graph will be zero.

So, (d) is not correct.
