Thermal Equilibrium involves two substances that are in physical contact reaching the same final temperature over time.
Thermal Equilibrium Reactions
Concept #1: Thermal Equilibrium
Under non-ideal conditions, calorimeter absorbs some of the heat from the object.
Example #1: If 50 g block of lead at 250 ºC is submerged in a solution at 90 ºC, the final temperature of the solution will be:
