Statement of a problem № 10070


A bicycle tire with a volume of 0.00212 m3 is filled to its recommended absolute pressure of 495 kPa on a cold winter day when the tire s temperature is −15 °C. The cyclist then brings his bicycle into a hot laundry room at 32 °C. (a) If the tire warms up while its volume remains constant, will the pressure increase be greater than, less than, or equal to the manufacturer s stated 10% overpressure limit? (b) Find the absolute pressure in the tire when it warms to 32 °C at constant volume?
