A MOTORIST EQUIPS HIS AUTOMOBILE TIRES WITH A RELIEF-TYPE VALVE SO THAT THE PRESSURE INSIDE THE TIRE NEVER WILL EXCEED 240 KPA (GAGE). HE  STARTS A TRIP WITH A PRESSURE OF 200 KPA(GAGE) AND A TEMPERATURE OF 230C IN THE TIRES. DURING THE LONG DRIVE , THE TEMPERATURE OF THE AIR IN THEW TIRES REACHES 830C. EACH TIRE CONTAINS 0.11 KG OF AIR. DETERMINE (a) the mass of air escaping each tire, (b) the pressure of the tire when the temperature returns to 230C. Ans (a) 0.0064 Kg; (b) 182.48 Kpa (gage)
