Question

To double the volume of a given mass of an ideal gas at 27°C keeping the pressure constant, one must raise the temperature in degree centigrade to

• A. 54°
• B. 270°
• C. 327°
• D. 600°

Answer 1

Answer: (C)

327°

Answer 2

$V \propto T$ Ž $\frac{V_{1}}{V_{2}} = \frac{T_{1}}{T_{2}}$Ž $\frac{V}{2V} = \frac{(273 + 27)}{T_{2}} = \frac{300}{T_{2}}$

Ž $T_{2} = 600K$ = 327°C
