A chemistry teacher uses a model similar to the one pictured above to represent the concept of differences in heat capacity. The teacher asks the class to imagine that the water represents heat and to predict how the flow of water might relate to heat capacity, temperature, and thermal conductivity. The model includes a large container with a slow leak and a small container with a fast leak. The teachers asks "Which of the two leaking containers could produce the largest water level change in identical pans placed below the streams of water?" This is what two friends in class said:
Kelvin: The water in the smaller container will cause the water level to change more because is has a faster flow.
Joule: The water in the larger container will cause the water level to change more because it holds the most water.
