Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points An automobile fuel tank is filled to the brim with 66 . 9 L (12 gal) of gasoline at 8 . 66 ◦ C. Immediately afterward, the vehicle is parked in the Sun, where the temperature is 31 . 2 ◦ C. The coefficient of volume expansion of gaso- line is 0 . 00096 ◦ C − 1 . Note: Neglect the expansion of the tank. How much gasoline overflows from the tank as a result of the expansion? Answer in units of m 3 . 002 10.0 points In your room there are things such as tables, chairs, other people, and so forth. Which of these has a temperature greater than the temperature of the air? 1. tables, chairs and other people 2. tables 3. All are wrong. 4. people 5. chairs 003 (part 1 of 2) 10.0 points At 30 ◦ C, an aluminum ring has an inner di- ameter of 2 cm and a brass rod has a diameter of 2 . 02 cm. If the temperature coefficient of expansion for brass is α b = 1 . 9 × 10 − 5 ( ◦ C) − 1 and the temperature coefficient of expansion for alu- minum is α a = 2 . 4 × 10 − 5 ( ◦ C) − 1 , to what temperature must the ring be heated so that it will just slip over the rod? Answer in unitsit will just slip over the rod?...
