Q4. [16+16 = 32 points) The air temperature and volume inside an automobile tire are 25°C, and 0.025 m respectively, when the pressure gage reads 210 kPa (note: this is a gage pressure). The atmospheric pressure is 100 kPa. Given: R.it = 0.287 kJ/kg K. Determine: (a) the mass of air inside the tire. (b) The gage pressure in the tire when the temperature of air inside the tire reaches 50°C (assume constant volume)
