AP Chemistry / Unit 6: Thermochemistry
6.3 Heat Transfer and Thermal Equilibrium
Notes
Heat flows from hotter to colder objects until they reach the same temperature (thermal equilibrium).
- Heat lost by one = heat gained by the other.
Practice
A hot metal is dropped in cool water. Heat flows:
Hot to cold.
At thermal equilibrium, the two objects have the same:
Flow stops.
In a perfect insulated system, $q_{metal}+q_{water}=$
Energy is conserved.
