Question 5
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.
