- Heat is a substance.
- Heat is not energy.
- Temperature is a property of a particular material or object. (Metal is naturally cooler than plastic).
- The temperature of an object depends on its size.
- Heat and cold are different, rather than being opposite ends of a continuum.
- When temperature at boiling remains constant, something is "wrong".
- Boiling is the maximum temperature a substance can reach.
- Ice cannot change temperature.
- Objects of different temperature that are in contact with each other, or in contact with air at different temperature, do not necessarily move toward the same temperature.
- Heat only travels upward.
- Heat rises.
- The kinetic theory does not really explain heat transfer. (It is recited but not believed).
- Objects that readily become warm (conductors of heat) do not readily become cold.
- The bubbles in boiling water contain "air", "oxygen" or "nothing", rather than water vapor.
