Question 740 Deck General
70% to passDuring transfer operations, ethyl chloride spills into the water. According to the Chemical Data Guide, at what temperature will the ethyl chloride boil off the water?
A
above 46°F
B
above 54°F
C
above 60°F
D
above 68°F
AI Explanation
The correct answer is B) above 54°F. The Chemical Data Guide for Hazardous Materials states that the boiling point of ethyl chloride is 54°F (12.2°C). Therefore, for the ethyl chloride to boil off the water during a spill, the water temperature must be above 54°F. The other answer choices are incorrect because they do not accurately reflect the boiling point of ethyl chloride. Temperatures below 54°F would not be sufficient for the ethyl chloride to fully evaporate from the water.
