Challenge Problems
Push your limits with challenges.
Question 1
A block of ice weighing 1 kg melts into water at 0°C. If the latent heat of fusion is 334,000 J/kg, how much energy is required for this process?
💡 Hint: Remember to use the formula for latent heat!
Question 2
Water requires 2,256 J to vaporize 1 kg into steam. Why is this energy crucial for boiling water and how does it relate to latent heat?
💡 Hint: Consider the transition from liquid to gas.
