Challenge Problems
Push your limits with advanced challenges
If a metal rod ends at temperature 100°C and the other end at 25°C, how long will it take for the entire rod to reach uniform temperature given that it has a length of 1 meter and a thermal conductivity of 45 W/mK?
💡 Hint: Consider using the formula to find out.
A room has a constant heat supply of 2000 J/s, and the air can lose heat through convection and radiation at a rate of 1000 J/s. How would this affect the room temperature over an hour if other factors remain constant?
💡 Hint: Think about the total heat absorbed in one hour.
