Using the graph shown in the illustration, the oil being separated has a specific gravity of 0.87 kg/dm3 at 72.5°C. What will be the specific gravity if the temperature is lowered to 40°C? Illustration MO-0113
AI Explanation
The correct answer is C) 0.892 kg/dm3.
According to the graph shown in the illustration MO-0113, when the temperature of the oil is lowered from 72.5°C to 40°C, the specific gravity of the oil increases from 0.87 kg/dm3 to 0.892 kg/dm3. This is because the density of the oil increases as the temperature decreases, as per the relationship between temperature and density of liquids.
The other options are incorrect because they do not accurately reflect the change in specific gravity based on the given temperature decrease, as shown in the provided graph.
