Challenge Problems
Push your limits with challenges.
Question 1
In a calorimetry experiment, if 200 g of ice at -10°C is heated until it melts at 0°C and all water reaches 0°C, calculate how much energy is absorbed. (Specific heat of ice = 2.09 J/g°C, Latent heat of fusion = 334 J/g)
💡 Hint: Break the problem into parts, calculate energy for heating ice and for melting.
Question 2
Design and conduct an experiment to compare the cooling rate of two different materials. What data would you gather, and what factors would you control?
💡 Hint: Focus on how you'll measure rates and ensure consistent conditions.
