1. The experiment tested how the color of different surfaces affected the temperature of water over an hour. 2. Water was heated to 100°C then placed on black, white, pink, green and blue surfaces and temperature was measured every 5 minutes. 3. Across 3 trials, the black surface consistently maintained the lowest temperature while white maintained the highest, with pink, green and blue in between. The results supported the hypothesis that black absorbs heat and white reflects it.
