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
Verified Correct Answer: B.
Physical Principles & Numerical Solution
\(\frac{p_1}{T_1}\) = \(\frac{p_2}{T_2}\)
\(\frac{2 \times 10^5}{27 + 273}\) = \(\frac{p_2}{87 + 273}\)
P2 = 2.4 x 105Nm-2
