<human>: How do I determine the melting point of sugar using a thermometer?
<bot>: To determine the melting point of sugar, use a thermometer. Place the thermometer in a cup of sugar and stir it until all of the sugar is melted. Record the temperature reading from the thermometer and then repeat this process several times to get an average reading. The melting point of sugar can vary depending on the humidity level, so you may need to experiment with different batches of sugar to get an accurate reading.
