The pressure of air in a tire is 22.5Nm2 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.

21.10Nm2

B.

24Nm2

C.

39.07Nm2

D.

45Nm2

E.

97.25Nm2

Correct answer is B

P1T1=P2T2;P2=22.5×320K300K=24Nm2
