Challenge Problems
Push your limits with advanced challenges
A 3 kg block of ice at -10°C is heated until it melts and then warms to 0°C. Calculate the total heat energy used. (Use specific heat for ice = 2.1 J/kg·K and latent heat of fusion = 334,000 J/kg)
💡 Hint: Calculate each part step-by-step; remember to calculate the two stages separately.
Consider a room where hot air from a radiator rises to the ceiling and cool air sinks. This cycle continues. Explain how this demonstrates convection and its real-life implications.
💡 Hint: Think about how this effect is utilized in heating systems.
