My team has finished an experiment to test which test tube's [when covered in black or white tape] water was the hottest. We covered one test tube in black electrical tape and one in white masking tape. We taped those to a ring stand. We put a thermometer in each test tube and then got a lamp. We plugged the lamp in and focused it on both test tubes evenly. We looked at the temperature of each test tube every 15 minutes. These are our results:
At time zero the water in the black tube was at: 26ºC
At time zero the water in the white tube was at: 25ºC
At time 15 mins the water in the black tube was at: 30ºC
At time 15 mins the water in the white tube was at: 26ºC
At time 30mins the water in the black tube was at: 34ºC
At time 15 mins the water in the black tube was at: 30ºC
At time 15 mins the water in the white tube was at: 26ºC
At time 30mins the water in the black tube was at: 34ºC
At time 30 mins the water in the white tube was at: 27ºC
