The blue curve represents the temperature of the blue flask.
The yellow curve represents the temperature of the yellow flask.
Conduction and Convection Gizmo, a simulation tool from Explore Learning.
The graph in the Data tab shows the temperatures of two flasks of colored water, one blue and one yellow, over time.
The blue curve represents the temperature of the blue flask.
The yellow curve represents the temperature of the yellow flask.
The two flasks are separated by a solid chunk of material, which can be either copper or stone.
Copper is a good conductor of heat, while stone is a poor conductor of heat.
If you run the simulation with the copper solid chunk, you will see that the blue and yellow curves quickly converge to the same temperature.
This is because heat flows easily from the hotter blue flask to the colder yellow flask through the copper solid chunk.
If you run the simulation with the stone solid chunk, you will see that the blue and yellow curves converge more slowly to the same temperature.
This is because heat flows more slowly through stone than through copper.
The Conduction and Convection Gizmo is a useful tool for teaching students about the concepts of heat conduction and convection.
