Challenge Problems
Push your limits with challenges.
Question 1
You have a metal and water system where 500 J of heat is added to 0.5 kg of metal (specific heat = 400 J/kg/K) and 1 kg of water (specific heat = 4186 J/kg/K). If both start at 20 °C, what will be their final equilibrium temperature?
💡 Hint: Set up an equation where heat lost by one equals heat gained by another.
Question 2
A calorimeter contains 200 g of water at 25 °C. If it absorbs 1000 J of heat, what will the final temperature be?
💡 Hint: Calculate the temperature rise and then add to the initial temperature.
