5. A 600-g piece of tin absorbs 1000 J of heat. By how much will its temperature change? (ctin = 227 J/kg-K) 7.3 K 7.3 mK 2.6 K 2.6 kK 380 kK
4. Heat up the water to 100°C and the iron to 160°C. Then, put the iron in the boiling water. What happens to their temperature eventually? The iron which had the higher temperature goes down quickly to same temperature as the water and achieved a thermal equilibrium at 100°C. In real situation the water will evaporate faster as it quickly cools down the iron as because the water already achieved its boiling point. 5. Define what thermal equilibrium is and explain its connection to question No. 4.
