Question 1 of 205eccefa2bacbc34ba4d479d6

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

🔍 Key Concepts

• Use the oil (solid) Q curve on the MO-0113 graph, not the water (dashed) curve • Follow the constant-oil line that passes through the known point (0.87 kg/dm³ at 72.5°C) to a new temperature • As temperature decreases, oil density (specific gravity) should increase on this chart

💭 Think About

• On the x‑axis, locate 72.5°C and move up until you hit the solid oil curve that corresponds to SG 0.87; from that point, which direction along the slanted grid lines represents keeping the same oil while changing temperature? • After following that constant‑oil line to 40°C on the x‑axis, what approximate SG value do you read on the y‑axis, and is it higher or lower than 0.87? • Compare your reading with the choices: which option best matches the SG you read from the graph when you move from 72.5°C down to 40°C along the proper line?

✅ Before You Answer

• Be sure you are reading the solid oil line, not the dashed water line • Verify that you have followed the correct slanted guide line (constant oil) from 72.5°C to 40°C, not moved straight vertically or horizontally • Confirm that your final SG at 40°C is greater than 0.87 kg/dm³, consistent with density increasing as temperature drops
