1. While cooking with boiling water, there are two ways to get a mild burn. I will feel a mild burn if I splash boiling water onto my skin. I will also feel a burn if I accidentally place my hand in a stream of steam coming from a kettle or covered pot. Even if the steam is at 100C, and the mass of H2O is the same, the steam burn will be more damaging (and be more painful!). Use concepts and vocabulary from the chapter to explain why.
2. How does the kinetic theory describe a gas? What does temperature measure according to the theory?
3. What creates pressure according to the kinetic theory? Why does pressure increase with temperature in a closed container?
4. A heat pump is a device that uses work to transfer heat from a low-temperature reservoir to a high temperature reservoir. How does this relate to the Second Law of Thermodynamics?
Ignoring friction and air resistance, find the maximum height H to which she rises above the end of the track.
An engine running at 38.3 percent efficiency receives 287 J of heat from the hot reservoir through each cycle. How much heat is transferred to the cold reservoir through each cycle?
A football is kicked straight up into the air and it hits theground 3.8 seconds later. What is the greatest height reached by the ball (assume itwas kicked at ground level)?
