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: Option B
Explanation
(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
