Gas Laws & Ideal Gas Equation

A bicycle tyre is filled with air having pressure of 270 kPa270\text{ kPa} at 27∘C27^\circ\text{C}. The approximate pressure of the air in the tyre when the temperature increases to 36∘C36^\circ\text{C} is

Show answer and solution

Answer: (d)

  1. Volume fixed, so P∝TP \propto T; T1=300T_1 = 300 K, T2=309T_2 = 309 K.
  2. P2=270×309300=278.1P_2 = 270 \times \dfrac{309}{300} = 278.1 kPa
  3. So the answer is (d) 278 kPa.
