11. You’re riding down the road in your car, alternately eating a snack and singing along to the
radio. List all the forms of energy in the car (and explain why you know that form is there), and
what processes are going on converting one kind of energy to another.
12. Estimation problem. Use what you know from chapter 1, some reasonable estimates, and the
information I give you below to guess how much total energy is used by homes in the city of
Evansville in a year. Be clear and show your work, and when you guess at something, say why
you think that’s a reasonable guess. Your answer should be in some multiple of Watt-hours (so
kWh or MWh or something like that would work). Average monthly electricity bill: \$150
Evansville population: 120,000
13. Suppose you have a number of mystery substances. They can be of any phase of matter, any
kind of material from the periodic table. They are all at the same temperature. A. What
characteristic(s) of the substances would allow you to sort these substances according to the
speed of individual atoms? B. What characteristic(s) would allow you to sort these substances
according to total thermal energy contained? [Note: this answer should involve something
different from the answer to part (a). It’s not the same question.]
14. State the laws of thermodynamics and what they mean, in your own words.
15. Take an imaginary walk through your average day. List the sources of heat in your daily life,
and whether they get to you by radiation, conduction, or convection. [Take your time with this
— thoroughness is a good thing.]
16. A car rear-ends and sticks to a truck, and this question concerns their speeds just before and
just after their collision (momentum is conserved). The car has a mass of 1000kg, the truck is
3000kg. Initially, the car is going 20m/s, but the truck is only going 5 m/s (coming from a stop
light) in the same direction. Calculate the final speed of the car/truck combination after the
collision.
