About Tier 3 - Dimension
Requires several pieces of reasoning to be organised into a solution.
Difficulty describes the challenge, not the solver. It is a Society guide rather than a formal academic level.
The tier is a Society guide to the amount of reasoning, technical work and insight a problem is expected to require. Your experience may vary depending on the topic and your background.
Mixing Hot and Cold
Thermal Physics / Calorimetry - 7 min
Mix of liquid water at with of liquid water at . No heat escapes, the container absorbs negligible heat, and no phase change occurs. Treat both portions as having the same constant specific heat capacity. What is the final equilibrium temperature?
Assumptions
Treat liquid water's specific heat capacity as the same constant for both portions over this temperature range. Ignore mechanical work, evaporation and the container's heat capacity; the combined water is thermally isolated.
