Question 269Motor Plants - Assistant Engineer

The correct answer is D) 0.925 kg/dm3. The key to solving this problem is understanding how temperature affects the specific gravity of a liquid. As the temperature of a liquid increases, its specific gravity decreases. The graph provided in the illustration MO-0113 shows the relationship between temperature and specific gravity for this particular liquid. Given that the specific gravity of the liquid is 0.96 kg/dm3 at 77°F, and the temperature is increased to 167°F, the specific gravity can be determined from the graph to be 0.925 kg/dm3, which corresponds to answer choice D. The other answer choices are incorrect because they do not match the value indicated by the graph for the increased temperature of 167°F.
