A nearly flat bicycle tire becomes noticeably warmer after it has been pumped up. Approximate this process as a reversible adiabatic compression. Assume the initial pressure and temperature of the air before it is put in the tire to be P_i = 1.00 bar and T_i = 280.K. The final pressure in the tire is P_f = 3.75 bar. Calculate the final temperature of the air in the tire. Assume that C_{V ,m} = 5/2R.
