A gas at pressure PNm(^{-2}) and temperature 27°C is heated to 77°C at constant volume. The new pressure is

  • A.
    0.85 PN-m-2
  • B.
    0.86 PN-m-2
  • C.
    1.16 PN-m-2
  • D.
    1.18 PN-m-2
  • E.
    2.85 PN-m-2
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})
