What else can I help you with?
You are trying to calibrate a celsius thermometer. when you place the thermometer into a beaker of boiling water what should the thermometer read?
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.
Why was it important not to let the thermometer rest on the bottom of the breaker?
It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.
Why should a thermometer not touch the sides of the test tube and should be placed in the middle?
If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.
What change takes place in the liquid inside a thermometer when the thermometer is placed into something cold?
When a thermometer is placed into something cold, the liquid inside contracts and decreases in volume. This causes the liquid level to decrease, indicating a lower temperature on the scale of the thermometer.
What is the best way to heat a beaker of water on a Bunsen burner?
The best way to heat a beaker of water on a Bunsen burner is to adjust the air hole to get a blue flame, place the beaker on a wire gauze to distribute heat evenly, and continuously stir the water with a glass rod to ensure uniform heating. Additionally, you should monitor the temperature with a thermometer to prevent overheating.

How does is the temperature of beaker measure in water?
The temperature of a beaker is typically measured using a thermometer that is placed in the water inside the beaker. The thermometer will provide a reading of the water temperature, which indirectly reflects the temperature of the beaker as well.

Why should not a hot thermometer be placed in ice water?
Because it will bust.
What do you use to support a thermometer to a beaker?
a metal stand.
What is a beaker placed on top of?
a tripod

What aftercare is associated with thermometers?
A thermometer should be cleaned, disinfected and placed in an appropriate container for storage.
Where should a beaker be placed with respect to the flame for the most efficient heating on Bunsen burner?
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.
How does the heat reach the thermometer in the heated beaker?
Heat reaches the thermometer in the heated beaker primarily through conduction and convection. As the beaker is heated, the water molecules gain energy and transfer that energy to the thermometer through direct contact. Additionally, as the warmer water rises and cooler water descends, convection currents help distribute heat throughout the liquid, ensuring that the thermometer accurately reflects the water's temperature. This process allows the thermometer to register the temperature of the liquid efficiently.
What will a thermometer show if placed next to a beaker containing an exothermic reaction?
The exothermic reaction within the beaker releases heat energy, resulting in an increase in temperature of the materials inside the beaker.Now about the dispersion of the heat energy.Conduction: The beaker molecules and air molecules in touch with the heated material inside the beaker heat up by conduction and will continue spreading this heat in all directions.Via Convection: The heated air above the reacting materials rises, thus dispersing the heat via convection.Radiation: Any and all heated materials disperse heat via radiation. This type of heat transfer requires no medium.How far and how much energy is transferred depends on different variable, including the amount of energy given off by the exothermic reaction as well as the materials in the beaker, and air density.As to the dispersed heat affecting a thermometer placed next to the beaker---There are so many variables not given in the question.Is the thermometer bulb measuring air temperature? if so, is the heat given off by the exothermic reaction enough to raise the air temperature surrounding the thermometer bulb? If so, then the answer is that the thermometer will report a higher temperature reading.
How do you heat a liquid to 90 degrees?
if your in a lab, put water in a beaker, place the beaker on a tripod and heat with Bunsen burner, (use thermometer to measure
