A Motor Tyre is inflated to pressure of 2.0 x 105Nm-2 when the temperature of air is 27oC. What will be the pressure in it at 87oC assuming that the volume of the Tyre does not change?

A.

2.6 x 105Nm-2

B.

2.4 x 105Nm-2

C.

2.2 x 105Nm-2

D.

1.3 x 105Nm-2

Correct answer is B

\(\frac{p_1}{T_1}\) = \(\frac{p_2}{T_2}\)

\(\frac{2 \times 10^5}{27 + 273}\) = \(\frac{p_2}{87 + 273}\)

P2 = 2.4 x 105Nm-2
