If there is a sudden rise in temperature of a liquid being distilled, what should you do?

• A. Immediately remove heat, alert people nearby, and quickly move away
• B. Increase heat to speed up boiling
• C. Continue distillation and monitor later
• D. Pour more solvent

Answer: (A)

A sudden rise in temperature during distillation is a warning sign of a potentially dangerous situation, such as overheating or ignition of flammable vapors. The safest immediate action is to stop adding heat to reduce energy input and prevent the situation from escalating. At the same time, alerting others nearby helps keep everyone aware and prepared to act, and moving away reduces personal risk from heat, splashes, or a possible fire. Increasing heat would worsen the danger by driving faster boiling or ignition; continuing the process without addressing the temperature rise ignores the risk; pouring more solvent could fuel a spill or fire and does not address the underlying hazard.
