Passage V
Researchers conducted an experiment to determine the factors affecting heat flow. In each trial, one or more blocks of a particular material was (were) placed between two walls at constant temperatures T1 and T2 in one of the configurations shown in Figure 1. Heat was transferred through the block(s) from the hotter wall to the cooler wall. This heat flow, measured in joules per second (J/sec), is shown in Table 1.
(Note: All blocks used in the experiment were identical in size and shape. In each configuration, the contact area was the surface area of the end of the block(s) against one wall.)
25. According to the information provided, heat flowed from the wall at temperature T2 to the wall at temperature T1 in which trial?
Your Answer is
Correct Answer is B
Explanation
Heat flows from T2 to T1, indicating that the temperature of T2 should be higher than T1. Referring to table 1, it should be trail 6
