Question

What error is introduced if the bulb of the thermometer, or the thermocouple, is too high in the distillation apparatus? The recorded boiling point will be higher than actual because hotter vapors travel higher up the condenser. The recorded boiling point will be lower than actual because the bulb is not exposed to the hot vapor. The recorded boiling point will be lower than actual because hotter vapors travel higher up the condenser. The recorded boiling point will be higher than actual because the bulb is not exposed to the hot vapor.

Answer 1

The correct phrase is: The recorded boiling point will be higher than actual because hotter vapors travel higher up the condenser

Step-by-step explanation:

When we have a system that is going from the liquid phase to the vapor phase, there is an energy that is spent for this change of state. Therefore the temperature of the liquid remains constant until it has changed state, but the steam that comes out can continue to heat up, so it has a temperature more wing than the liquid.

If the thermometer is very high it will measure the temperature of the vapors, as the temperature is a form of energy these hotter vapors will rise more in the condenser tube.

The correct phrase is: The recorded boiling point will be higher than actual because hotter vapors travel higher up the condenser
