Question

One litre of Helium gas at a pressure 76 cm of Hg and temperature 27 is heated till its pressure and volume are doubled. The final temperature attained by the gas is

• A. 927C
• B. 900C
• C. 627C
• D. 327C

Answer 1

Answer: (A)

927C

Answer 2

$\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}} \Rightarrow \frac{76 \times 1}{300} = \frac{152 \times 2}{T_{2}}$

$\Rightarrow T_{2} = 1200K = 927{^\circ}C$
