Answer (1)
Initial State (0 minutes)Temperature: 25°C (Room temperature)Candle Condition: The candle is intact and unlit.Ignition and Initial Melting (2 minutes)Temperature: 40°CCandle Condition: The wick begins to melt and burn, initiating the process.Wax Begins to Melt (4 minutes)Temperature: 60°CCandle Condition: The wax closest to the flame starts to melt.Active Wax Dripping (6 minutes)Temperature: 80°CCandle Condition: The melted wax is now dripping, and the overall length of the candle is visibly decreasing.Significant Wax Pool and Midway Point (8 minutes)Temperature: 100°CCandle Condition: A noticeable pool of melted wax has formed, and the candle has burned down to approximately its midway point.Near Complete Wax Consumption (10 minutes)Temperature: 120°CCandle Condition: The flame is burning steadily, and the wax at the base of the candle is almost entirely consumed.Experiment Overview:• Consistent temperature increase due to candle burning.• Chemical change in candle burning, involving wax reaction with oxygen.• Physical and chemical transformations of wax: solid wax melts, liquid wax turns into vapor, and wax vapor reacts with oxygen, undergoing combustion.
