* Temperature: A measure of the average kinetic energy (energy of motion) of the atoms or molecules within a substance. Higher temperature means faster moving particles.
* Heat: The transfer of thermal energy from one object or system to another due to a temperature difference.
Here's how it works:
1. When two objects at different temperatures come into contact, the particles with higher kinetic energy (hotter object) collide with those with lower kinetic energy (colder object).
2. This collision causes energy to transfer from the hotter object to the colder object.
3. This energy transfer continues until both objects reach thermal equilibrium, meaning they have the same temperature.
Key point: Atoms themselves don't move from one object to another during heat transfer. Instead, the energy associated with their motion is transferred.
