Question: What happens to a hot object when left in a colder environment?

Heat energy will flow from the hotter object to the colder surrounding environment until there is no longer any temperature difference between them.

This usually happens when the hot object's temperature has fallen to the temperature of its environment, which might be room temperature, if the surrounding environment happens to be a room.

Note: The temperatures do not meet in the middle if the environment is much bigger than the object. The final temperature of the object will be the same as the bigger environment.
