Challenge Problems
Push your limits with advanced challenges
A 10 kg block of material at 100°C is placed in 5 kg of water at 20°C. Determine the final equilibrium temperature if no heat is lost to the surroundings (specific heat of water = 4.18 kJ/kg°C).
💡 Hint: Use the specific heat formula Q = mcΔT.
Consider a metal rod with a coefficient of linear expansion of 1.5 x 10^-5 K^-1. Calculate how much it expands when heated from 20°C to 100°C, given its original length of 2 meters.
💡 Hint: Keep in mind the initial length of the rod.
