A hot potato is sitting out on the counter. After 3 hours, you pick up the potato and notice that it is no longer hot. Why is the potato not hot anymore?
the cold room made the potato cold
the potato is molded, and mold makes food cold
the heat from the potato went to the air
the potato is still hot
