What controls the rate at which things cool?
« on: 18/05/2016 09:43:10 »
After a cookout on Saturday, I left two cans of Coca-Cola in my bag. Around Monday morning which is almost two days later, when I left for school, the cans were still cold with moisture on it. My mom found the cans and thought that I had taken them out of the refrigerator and was planning to take them to school. We started arguing about how she believed I was lying and that it wasn't reasonable that would happen. The next day, she told me to put another can of Coca-Cola in the car and only leave it overnight to see what the result would be. Completely contrary to what I firmly believed it would feel like, it ended up being warm. Therefore, my mom put me on punishment and won't let me off until I find a reason that the can was cold. The temperatures on the Saturday were 53 degrees. The temperature on Saturday was 58 degrees. The temperature on Sunday night and early Monday morning when she saw the cold cans was 53 degrees. The temperature on the Monday night and early Tuesday morning where the warmer can was analyzed was 63 degrees. Can you explain why this could've happened. Please help me, I haven't been able to have any electronics except for the computer for 3 weeks now.

Are you sure that the second experiment was fully replicating all conditions that existed on the first occasion, such as the exact container in which the cans may have been store, whether open or closed, any air leakages, was the car in the sun or in the shade, etc.
