共有四小題:
In a particular set of experimental trials, students examine a system descried by the equation:
Q/Δt=[kπd²(Th-Tc)]/4L
In this trials, all quantities except d and Δt are constant.
(a) If d is made three times larger, does the equation predict that Δt will get larger or smaller?
(b) What pattern of proportionality of Δt to d does the equation predict?
(c) To display this proportionality as a straight line on a graph,what quantities should you plot on the horizontal and verticalaxes?
(d) What expression represents the theoretical slope of thisgraph?
