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

A.
Thermal energy moved out of the water in the bottle.
B.
Thermal energy did not move during this experiment.
C.
Thermal energy moved into the air in the room.
D.
Thermal energy moved into the water in the bottle.
