Question

Volume-temperature graph at atmospheric pressure for a monoatomic gas $\left(Vin{m}^3,Tin{}^{\circ }C\right)$ is

• A.
• B.
• C.
• D.

Answer 1

Answer: (C)

At constant pressure, the volume of a given mass of a gas is directly proportional to its absolute temperature $(T)$ . $ie,$ $\frac{V}{T}=$ constant.
This is another form of Charles law. Hence, variation of volume with temperature is as follows. Hence, correct graph will be (c).
