= A copper sheet (a = 116 mm²/s) of thickness 2L = 2 mm has an initial temperature of Ti = 118°C. It is suddenly quenched in liquid water, resulting in boiling at its two surfaces. Determine the time needed for the sheet to reach a core temperature of T = 102°C. Plot the copper temperature versus time for 0 ≤ t ≤0.5 s.
