Q. Which one of the following volume $(V) -$temperature $(T)$ plots represents the behaiour of one mole of an ideal gas at one atmospheric pressure?
A) [image:5_image3.emf]
B) [image:5_image4.emf]
C) [image:5_image5.emf]
D) [image:5_image6.emf]
Explanation
(c)
$V - T$ plot representing the behavior of 1 mole of an ideal gas at 1 atm pressure.
Volume of 1 mole of an ideal gas at 273 K and 1 atm pressure is 22.4 L.
Volume of 1 mole of an ideal gas at 373 K and 1 atm pressure will be
$V = \frac{RT}{p} = \frac{0.0821 \times 373}{1} = 30.58\ L$
