Challenge Problems
Push your limits with advanced challenges
Given two substances: A solid ice (1 kg) at -5°C and steam (1 kg) at 100°C, calculate and compare their total thermal energy. Assume specific heats of ice = 2.1 J/g°C and steam = 2.0 J/g°C.
💡 Hint: Remember to use the thermal energy formula for both substances.
A heated metal block at 80°C and a block of wood at room temperature (20°C) both weigh 500g. If both are placed in thermal contact, explain what happens over time and why, incorporating the concept of thermal energy and temperature.
💡 Hint: Think about energy movement and temperature change.
