When the low tire pressure light came on, the pressure was low because the temperature is low. What can you infer about the volume and moles of gas within the tire? When you fill the tire with additional air at the gas station how are the variables (pressure, volume, number of moles, and temperature) changing? 3. Your tire has a volume of 10 liters and contains approximately 0.4 moles of air at 1 atm and 30.8 ºC (303.8K). What is...
