The pressure of air in a tire is (22.5Nm^{-2}) at 27°C. If the air in the tyre heats up to 47°C, calculate the new pressure of the air, assuming that no air leaks out and that the change in volume of the air can be neglected.
-
A.
(21.10Nm^{-2}) -
B.
(24Nm^{-2}) -
C.
(39.07Nm^{-2}) -
D.
(45Nm^{-2}) -
E.
(97.25Nm^{-2})
Correct Answer: Option B
Explanation
(frac{P_1}{T_1}=frac{P_2}{T_2};P_2= frac{22.5times320K}{300K}=24Nm^{-2})
