Challenge Problems
Push your limits with challenges.
Question 1
A 250 g piece of copper at 100Β°C is placed in 150 g of water at 20Β°C. Calculate the final temperature, assuming no heat loss.
π‘ Hint: You will need the specific heat capacities of both copper and water.
Question 2
A mixture of ice and water is put together. If 100 g of ice at 0Β°C melts into water and the initial water at 20Β°C is 300 g, calculate the final temperature of the system once it reaches thermal equilibrium.
π‘ Hint: Apply the concept of latent heat in your calculations.
