In order to get a more precise and accurate reading.
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.
To calibrate a volumetric flask, you need to fill it with a known volume of liquid, usually water, at a specific temperature. Then, you measure the actual volume of liquid in the flask using a calibrated measuring device, such as a graduated cylinder or a pipette. The difference between the known volume and the measured volume is the calibration error, which can be used to adjust the accuracy of the flask.
Pre-rinsing volumetric glassware removes any residues from previous use, ensuring accurate and uncontaminated results in the titration process. This step also helps to condition the glassware, preventing it from affecting the accuracy of the solution being measured.
Temperature and density affect the volume of a liquid, which in turn can impact the calibration of glassware. Variations in temperature can cause expansion or contraction of the glassware, leading to inaccuracies in volume measurements. Changes in density can also affect the weight of the liquid being measured, affecting the calibration process. It is important to calibrate glassware at a consistent temperature and account for differences in density to ensure accurate measurements.
In titrations, precise volumetric equipment like burettes and volumetric flasks are commonly used. Burettes are used to deliver precise volumes of titrant, while volumetric flasks are used to prepare accurate standard solutions or to collect titrated solutions for analysis.

To calibrate a freezer thermometer, you will need a glass of ice water. Place the thermometer in the ice water for a few minutes, making sure it does not touch the sides or bottom of the glass. The thermometer should read 32°F (0°C) in the ice water. If it does not, adjust the calibration nut or dial on the thermometer until it reads the correct temperature.
To calibrate an unmarked thermometer, you can place it in a known temperature source, such as an ice bath or boiling water, and compare the reading to the actual temperature at that point. Adjust the thermometer accordingly by using a small wrench to rotate the calibration nut until the correct temperature is displayed.
To modify an experimental thermometer to read actual temperature, you would need to calibrate it against a known accurate reference thermometer. Compare the readings between the two thermometers at various temperatures and make necessary adjustments to ensure the experimental thermometer provides accurate readings. Recalibrate periodically to maintain accuracy.
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.
To calibrate a bimetallic thermometer, immerse the probe in a stable reference temperature source (like an ice bath or boiling water) and compare the reading to the known temperature. If there's a discrepancy, adjust the calibration screw on the thermometer until it matches the reference temperature. Repeat this process at different temperatures to ensure accuracy across the thermometer's range.
Accuracy is lost when thermometers are bumped or dropped.

To calibrate your oven for accurate temperature settings, you can use an oven thermometer to compare the actual temperature inside the oven with the set temperature. If there is a difference, you can adjust the oven's temperature settings according to the thermometer readings.

When using the ice-point method to calibrate a thermometer, first ensure that you have a mixture of ice and water at 0°C. Immerse the thermometer's sensing element in the mixture, ensuring it does not touch the container's sides or bottom. Allow the thermometer to stabilize for a few minutes, then read the temperature and adjust the thermometer as needed to ensure it accurately reads 0°C. Finally, document the calibration results for future reference.
so we can get the net force.
