HW#13a Note: numbers used in solution steps are different from your WebAssign values. Page 1 of 6 1. Walker3 16.P.006. One day you notice that the outside temperature increased by 24 °F between your early morning jog and your lunch at noon. What is the corresponding change in temperature in each of the following scales? (a) Celsius 13°C (b) Kelvin 13 K Here when they say save size they mean same size of steps. Temperature difference in Kelvin is the same as temperature difference in Celsius. While the “step size” of Celsius is 9/5 times of step size of Fahrenheit. 2. Walker3 16.P.005. [565713] The temperature at a particular spot on the surface of the Sun is 6000 K. (a) Convert this temperature to the Celsius scale. 5727°C (b) Convert this temperature to the Fahrenheit scale. 10340°F 3. Walker3 16.P.013. [565953] A steel suspension-bridge is 3910 m long.

HW#13a Note: numbers used in solution steps are different from your WebAssign values. Page 2 of 6 4. Walker3 16.P.017. [565938] Early in the morning, when the temperature is 5.0°C, gasoline is pumped into a car's 51 L steel gas tank until it is filled to the top. Later in the day the temperature rises to 25 °C. Since the volume of gasoline increases more for a given temperature increase than the volume of the steel tank, gasoline will spill out of the tank. How much gasoline spills out in this case? 0.93 L 5. Walker3 16.P.024. [565886] During a workout, a person repeatedly lifts a 18.2 lb barbell through a distance of 1.5 ft. How many "reps" of this lift are required to burn off 150 Cal? 25467
