Question

multiple - choice question
why did three thermometers show a drop in temperature?
as the liquid (in the string) evaporated it took energy from the thermometer bulb
as the liquid (in the string) evaporated it gave energy to the thermometer bulb
the air gave energy to the liquid

Explanation:

Evaporation is an endothermic process. When the liquid in the string evaporates, it absorbs energy from the thermometer bulb, causing the temperature to drop.

Answer:

as the liquid (in the string) evaporated it took energy from the thermometer bulb
