A calorimeter contains 500 g of water at 25 °C. A 200 g copper piece at 150 °C is added. After reaching thermal equilibrium, what is the final temperature? Specific heat capacity of water is 4186 J/kg·K and for copper is 385 J/kg·K.
💡 Hint: Carefully isolate T_final on one side of the equation.
In a well-insulated container, 3 kg of ice at -10 °C is mixed with 2 kg of water at 70 °C. What will be the final temperature? Use the latent heat of fusion of ice (334,000 J/kg) for calculations.
💡 Hint: Keep track of phase changes and heat balance carefully.
