Question

Help me which one is the right answer?

Answer 1

The correct option is (b).

Step-by-step explanation:

The ideal gas law is given by :

`PV=nRT`

Where

P, V and T are pressure, volume and temperature of the gas

R is gas constant

`V=(nRT)/(P)`

If n,R and P are constant,

`V\propto T`

i.e.

At constant pressure, the volume of a gas is directly proportional to its temperature. Hence, the correct option is (b).
