What statement is true concerning the effect of elevating the temperature of the oily-water mixture associated with an oily-water separator?
AI Explanation
The correct answer is C) Heating the oily-water mixture decreases the viscosity of the oil and increases the specific gravity differential between the oil and water.
Explanation:
Heating the oily-water mixture decreases the viscosity of the oil, making it easier to separate from the water. Additionally, the increase in temperature causes the specific gravity differential between the oil and water to increase, further facilitating the separation process. This is the principle behind the use of oily-water separators, where heating the mixture aids in the effective removal of oil from the water.
The other options are incorrect because they do not accurately describe the effects of heating the oily-water mixture. Specifically, option A is incorrect because heating the mixture decreases the viscosity of the oil, not increases it. Options B and D are incorrect because heating the mixture increases the specific gravity differential between the oil and water, not decreases it.
