Challenge Problems
Push your limits with challenges.
Question 1
If you start with 1 kg of ice at -10°C, how much heat is required to turn it into steam at 100°C? Provide a detailed walkthrough of the calculation.
💡 Hint: Break it down into stages: heating ice, melting, heating water, and vaporizing! Then sum those amounts.
Question 2
A scientist is conducting an experiment with 300 grams of water and needs to figure out how much energy is required to freeze it at 0°C. What is the computation process?
💡 Hint: Think about using the heat of fusion for freezing instead of melting!
