Frank placed a metal spoon in a glass bowl of hot soup. He then went back to get crackers. When he touched the spoon he was surprised to find that it was hot. Frank knew that the spoon was not hot when he put it in the soup. Which sentence best explains how this happened?
Heat transferred from the hot soup to the metal spoon by conduction.
The metal spoon created its own heat while in the soup.
The glass bowl transferred cold to the spoon, making it feel hot.
The crackers made the spoon hot when Frank returned.
