Answer :
To record the melting point of tetradecanol, it is important the temperature is increase by little degrees after each trial.
The thermometer attached to the capillary tube was immersed in water without thermometer.
Usually heating curve describes the temperature change for a sample which passes through different states of matter.
The temperature than decreases and the solution in beaker cools down. To determine the melting point, it is important to keep the temperature consistent.
