Our goal is to extend the three phase model of pure substances to describe the cycle of the heat pack (including triggering). in this fnt you will combine process a) and processes c)-d) in one temperature vs. energy added diagram. a) sketch a temperature vs. energy added diagram for sodium acetate going between room temperature and 100°c. this is the combined process c) and d) from fnt 3) b) on a new diagram drawn exactly below the one you drew in a), sketch the path representing the process of the liquid heat pack cooling down from 100°c to room temperature, as you did for process a) of fnt 3). why does this process demonstrates supercooling? (it turns out that super cooling and super-heating are rather common. usually, however, they occur over a very small temperature range and thus go unnoticed.) c) take the two graphs from a) and b), and draw them "on top of each other" on a new graph. "the trick" is to figure out where they exactly overlap and where the two curves deviate from each other

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
