### Question

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.

### Options

A) $$21.10Nm^{-2}$$

B) $$24Nm^{-2}$$

C) $$39.07Nm^{-2}$$

D) $$45Nm^{-2}$$

E) $$97.25Nm^{-2}$$

$$\frac{P_1}{T_1}=\frac{P_2}{T_2};P_2= \frac{22.5\times320K}{300K}=24Nm^{-2}$$
• $$\frac{P_1}{T_1}=\frac{P_2}{T_2};P_2= \frac{22.5\times320K}{300K}=24Nm^{-2}$$
