Challenge Problems
Push your limits with challenges.
Question 1
A 1 kg block of metal at 100°C is placed in 500 g of water at 25°C. Considering the specific heat of metal is 0.5 J/g°C, calculate the final temperature when thermal equilibrium is reached.
💡 Hint: Remember that heat lost by metal equals heat gained by water.
Question 2
If it takes 334 kJ to melt ice, how much energy is needed to turn 2 kg of ice at 0°C to water at the same temperature? What about converting 2 kg of the resulting water at 0°C to steam?
💡 Hint: Keep in mind the specific latent heat values for both fusion and vaporization.
