The bulb of the thermometer placed at the head of a distillation apparatus should be adjacent to the condenser. Explain the effects on the temperature recorded if the thermometer were placed (a) well below the exit to the condenser and (b) above the exit

a) If the thermometer is placed well below the condenser it will record a higher temperature.

b) If the thermometer is placed well above the condenser it will record a lower temperature.

Explanation:

A) ) If the thermometer is placed below the opening to the condenser, a higher temperature will be recorded than if it is placed close to the opening since the bulb is contact with both the vapuor and liquid that is entering the condenser.

B) If the thermometer is placed above the condenser, a lower temperature will be recorded than if it is placed close to the opening since the bulb is not in full contact with both the vapuor and liquid that is entering the condenser.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .
