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

°C) than on a cold winter day (-5.00°C)?

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

lb barbell through a distance
of 1.5 ft. How many "reps" of this lift are required to burn off
150
Cal?
