Before starting a journey, the tyre pressure of a car was 3 x 105Nm-2 at 27oC. At the end of the journey, the pressure rose to 4 x 105Nm-2. Calculate the temperature of the tyre after the journey, assuming the volume is constant
A
400oC
B
300oC
C
273oC
D
127oC

Correct Option: D
(\frac{P_1}{T_1}) = (\frac{ P_2}{T_2})
(\frac{3 \times\ 10^6}{27 + 273}) = (\frac{4 \times\ 10^6}{0 + 273})
(\theta) = 127oC
