PV = nRT

At constant temperature

PV = K (T = constant)

Higher the value of PV, higher the temperature.

So, T 3 > T 2 > T 1

Since, P 1 = P 2 = P 3

So, V ∝ T ⇒ V 3 > V 2 > V 1

d =

Since, P 1 = P 2 = P 3

d ∝ ⇒ d 1 > d 2 > d 3

From Graph,

V 3 > V 2 > V 1 and T 1 = T 2 = T 3

Higher the volume, lesser the pressure because temperature is same for all.

P 1 > P 2 > P 3

d =

Since, T 1 = T 2 = T 3

So, d ∝ P ⇒ d 1 > d 2 > d 3

From the graph,

P 3 > P 2 > P 1 and T 1 = T 2 = T 3

Higher the pressure, lesser the volume because temperature is same for all.

V 1 > V 2 > V 3

d =

Since, T 1 = T 2 = T 3

So, d ∝ P ⇒ d 3 > d 2 > d 1

From the graph,

d 3 > d 2 > d 1 and P 1 = P 2 = P 3

d = ⇒ d ∝

So, T 1 > T 2 > T 3

PV = nRT

Since, P 1 = P 2 = P 3

V ∝ T

So, V 1 > V 2 > V 3
