Question 3
In the late 18th century, Count Rumford (Figure 10.4) whose real name was Benjamin Thompson, conducted a series of experiments, particularly during his work with cannons. He noticed that when metal was drilled, a lot of heat was released from the drill bits, enough to boil water. He observed that this heat was released continuously as the drill worked, regardless of how long it operated.
In pairs, find out how the unexpected results from Rumford’s experiments led to our understanding of heat as energy. Use the Internet to help you answer these questions. Share your answers with the class.
Suppose heat were truly what was suggested by the prevailing understanding then. What should Rumford have observed in his experiment with the cannon? Why didn’t this happen?
