Answer to Question #24571 in Physical Chemistry for Matt R
An automobile tire has a volume of 20 L where the air pressure (in the tires) is 180 kPa and temperature 21 degrees C. The standard gas constant for air is 287 mN/kgK. What is the air density and weight? After driving two hours, the tire temperature has risen 30 degrees C. Estimate the tire pressure, and state any assumptions you make.
