: Archimedes' principle, floating bodies, and pressure in liquids. Example Problem: Thermal Balance Question : A 500g piece of ice at -10∘Cnegative 10 raised to the composed with power C is placed in a calorimeter containing 1kg of water at 20∘C20 raised to the composed with power C olimpiadnye zadachi po fizike za 8 klass s reshenijami

: Heat balance equations involving mixtures, phase changes (melting/boiling), and fuel combustion. non-ideal instruments

: Complex circuits with multiple resistors, ammeters, and voltmeters, often requiring an understanding of ideal vs. non-ideal instruments. The mass of melted ice is

First, find the maximum heat the water can give off if it cools to 0∘C0 raised to the composed with power C

Remaining heat from water: .Now, check if this can melt all the ice ( , only part of the ice melts. Final Result The final temperature is 0∘C0 raised to the composed with power C . The mass of melted ice is .✅ Answer : The final temperature is 0∘C0 raised to the composed with power C with a mixture of water and ice. Where to Find More Problems Olympiad Archive - AoPS Wiki
