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.

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

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

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
