If a particular liquid has a specific gravity of 0.96 kg/dm3 at 77°F, what will be the specific gravity of the liquid, as determined from the graph shown in the illustration, if the temperature is increased to 167°F? Illustration MO-0113

Correct Answer: Option D — 0.925 kg/dm3

Thermal expansion causes liquid density to decrease as temperature rises. Utilizing standard petroleum gravity correction nomographs for marine fuel and lube oils confirms that heating the liquid to 167°F reduces its specific gravity to 0.925 kg/dm3.
