Ron investigated heat transfer using a bottle of water. He placed the bottle in a room where the temperature was 20.5°C. Ron
measured the temperature of the water in the bottle at 7am to be 12.5°C. At 3pm, he measured the water to be 20.5°C. In which
direction did the thermal energy move between the surroundings and the water in the bottle from 7am to 3pm
