Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the heat required to convert 3 kg of ice at -10 °C to water at 0 °C (specific heat of ice = 2100 J/kg·K).

💡 Hint: Start with temperature change, followed by phase change.

Challenge 2 Hard

If 1 kg of water at 0 °C absorbs 2,000 J of energy, what is the final temperature of the water assuming no phase change? (Specific heat of water = 4186 J/kg·K)

💡 Hint: Calculate the temperature change using the energy absorbed.
