Challenge Problems
Push your limits with challenges.
Question 1
You have 1 kg of ice at -20°C. Calculate the total energy required to convert it to steam at 100°C. Include the processes of heating ice to 0°C, melting it, heating water to 100°C, and vaporizing it.
💡 Hint: Break down the steps: Heating ice, melting it, heating water, vaporizing.
Question 2
A container holds 200 g of water at 100°C boiling. If 100 g of steam condenses, how much heat is released?
💡 Hint: Focus on the mass of steam and use the latent heat of vaporization.
