Question

A gas at pressure PN-m-2 and temperature 27°C is heated to 77°C at constant volume. The new pressure is

Options

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


The correct answer is C.

Explanation:

At constant volume,
\(\frac{P_1}{T_1}\) = \(\frac{P_2}{T_2}\)
\(\frac{P_1}{27 +273}\) = \(\frac{27}{27 + 273}\)
P2 = 1.16 PN-m-2

    The solution is authomagically wrong
    The question is from charle's laws

    At constants volume.P1/T1=P2/T2
    P1/27+273=P2/77+273
    P1/300=P2/350
    Cross multiply
    300P2=350p
    Divide both side by coefficient P2
    350p/300p2
    P2=1.16PN-m²

  • At constant volume,
    \(\frac{P_1}{T_1}\) = \(\frac{P_2}{T_2}\)
    \(\frac{P_1}{27 +273}\) = \(\frac{27}{27 + 273}\)
    P2 = 1.16 PN-m-2
