Volume-temperature graph at atmospheric pressure for a monoatomic gas \[\left( V\text{ }in\text{ }{{m}^{3}},\text{ }T\text{ }in\text{ }{}^\circ C \right)\] is

A)                                                

B)  

C)

D)  

Correct Answer: C

Solution :

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).
