Study Notes
Heat and Caloric Theory
- Lavoisier and followers believed heat was a latent or sensible energy that transferred between bodies.
- Cooling of water to room temperature was explained as heat flowing from the warmer water to the surroundings.
- Caloric theory considered heat a substance, analogous to matter.
- Heat was conserved, meaning the total amount of heat remained constant during transfer.
- Heat could change form (latent to sensible).
Modern Understanding of Heat
- Heat is not a substance but a form of energy transfer between objects.
- Heat flows from warmer to colder objects until thermal equilibrium is reached.
- No heat exists when there is no transfer of energy.
