Correct Answer: Option C
Explanation:
At constant volume,
\(\frac{P_1}{T_1}\) = \(\frac{P_2}{T_2}\)
\(\frac{P}{27 +273}\) = \(\frac{P_2}{77 + 273}\)
\(300P_2 = 350P\)
P2 = 1.16 PNm\(^{-2}\)
At constant volume,
\(\frac{P_1}{T_1}\) = \(\frac{P_2}{T_2}\)
\(\frac{P}{27 +273}\) = \(\frac{P_2}{77 + 273}\)
\(300P_2 = 350P\)
P2 = 1.16 PNm\(^{-2}\)
