A thermometer uses density of water as thermometric property. Actual reading in thermometer is height of water `(h)` which inversely proportional to the density of water `(d)`. In certain temp range is symmetrical ablout maximum. Two identical bodies (of same mass and specific heat) at different temp `T_(1)` and `T_(2)` show the same reading of height `h_(1)=h_(2)` in the thermometer. The bodies are brought in contact and allowed to reach the equilibrium. The thermometric reading height of water for final equilibrium state `h_(f)` satisfies
