Question

A bicycle tyre is filled with air having pressure of 270 kPa at 27°C. The approximate pressure of the air in the tyre when the temperature increases to 36°C is:

G1 Physics · Accepted Answer

At nearly constant volume, P/T = constant. T₁ = 300 K and T₂ = 309 K. Thus P₂ = 270×309/300 ≈ 278 kPa.
