Suspend the reservoir (the tip) of the thermometer below the surface of the solution, but do not allow the tip to touch the walls or bottom of the container. If the thermometer bulb touches the container, the temperature of the glass will be measured instead of the temperature of the solution.

Why must the thermometer not touch the side or the bottom of the beaker in measuring temperature?
It's important to not touch the sides of the test tube with the thermometer because touching it to the sides of the test tube fractures the glass and does not allow for correct temperature measurements.
Why is it important for the thermometer not to touch the bottom?
a) It's important to not touch the sides of the test tube with the thermometer because touching it to the sides of the test tube fractures the glass and does not allow for correct temperature measurements.
Why the bulb of thermometer should not touched while reading it?
Solution: It advised not to hold the thermometer by its bulb while reading it because the actual reading of human body temperature will get affected. This is for the reason that level of Mercury raises due to human body temperature.
Why should the thermometer element not touch the bottom of the pan when checking it in boiling water?
Why should the thermometer element not touch the bottom of the pan when checking it in boiling water? It may conduct heat directly from the pan bottom. ... When taking a temperature reading of a copper suction line, it is important to insulate the sensing element to give a more accurate reading.
Why must the thermometer be clamped into position?
A secure clamp on the flask is necessary in order to maintain the integrity of the system while lowering the heat source at the end of the distillation. Adjust the thermometer so the bulb is just below the arm of the adapter (Figure 5.23c).
Why is swirl calorimeter important?
The calorimeter must be swirled constantly during the temperature reading phase of the experiment to insure complete mixing of the contents.
Should the bulb be completely submerged in the solution?
In order to determine the boiling point of a solution, the thermometer bulb must be completely immersed. Special precautions must be taken to prevent the occurrence of boiling by bumping, and the consequent rise of temperature of the solution above its boiling point.
Why should you not stir with a thermometer?
Mercury is a dangerous substance that can be hazardous to your health if are in contact with it. Thermometers are very fragile and must be handled with care. ... Never use a thermometer to stir a liquid.
What will happen if you touch the bulb of the thermometer?
If you break a mercury thermometer or light bulb, a small amount of liquid mercury may spill out. Liquid mercury can separate into small beads, which can roll some distance away. The mercury may also evaporate into vapour. However, this small amount of mercury is extremely unlikely to cause problems for your health.
Should we touch the tip of thermometer?
Do not bite the glass thermometer. Keep the thermometer under your tongue for 3 minutes. Remove the thermometer without touching the tip.
What are the limitations of clinical thermometer?
State the limitation of clinical thermometer. Answer: The clinical thermometer cannot be used for measuring the temperature of any object more than 42°C (i.e. more than the body temperature). If it kept in the sun or near a flame, then this clinical thermometer can be break.
Where should the bulb of the thermometer be and why?
The mercury bulb of the thermometer should be positioned so that vapors condense readily on it. The tip of the bulb should be in line with the lowest part of the connecting tube of the stillhead.
What's the purpose of the thermometer where should the bulb of the thermometer be and why?
The bulb part of the thermometer is positioned near the side arm of the Y-adaptor so that it monitors the temperature of the vapors. See the illustrations below. If it is too low, it will be too close to the boiling liquid and will read higher than the true vapor temperature.
Why should the bulb of the thermometer be placed below the side arm of the three way adapter?
Why should the bulb of the thermometer be placed below the sidearm of the three-way adapter? The entire bulb of the thermometer must be positioned below the bottom of the arm leading to the condenser. This ensures that the entire bulbis immersed in the rising vapors and that the temperature is accurate 5.
