BulletPoint1 : 1. Since naphthalene powder has poor conductivity, it needs to be stirred frequently during heating to ensure uniform temperature distribution of naphthalene.
BulletPoint2 : 2. Heating process: The temperature difference between water and naphthalene should be basically constant. Adjust the thermostat hole to make the water temperature rise at a rate of 1°C/min. If the measured melting point deviates from the true value, it is mainly caused by the error of the thermometer. Therefore, the thermometer needs to be checked in advance.
BulletPoint3 : Perform calibration.
BulletPoint4 : 4. After the experiment, the thermometer and stirrer are solidified in naphthalene and cannot be pulled hard. They must be heated and melted again before use.
BulletPoint5 : Remove to avoid damage to the instrument.
BulletPoint6 : 5. After the experiment is completed, all parts should be cleaned and properly placed to prevent loss or damage.

Application: used for the experiment of dissolution and solidification of naphthalene, suitable for middle school students to conduct in groups
For experimental purposes. Through experiments, the curves of crystal dissolution and solidification processes can be directly drawn, and the laws of crystal dissolution and solidification can be intuitively understood.
Instructions
1. Add 2/3 of 75℃ hot water to a beaker and place the test tube containing 2cm deep naphthalene powder into the hot water in the beaker.
Heat, insert two thermometers into the beaker of water and the test tube respectively, and continuously rotate the stirrer into the naphthalene powder to make the temperature inside the naphthalene powder uniform.
