Q2 The rate of heat transfer of a body can be express as: dT -k(T – Ta) dt where T= temperature of the body (°C), Ta= temperature of the surrounding medium (°C) and k = proportionality constant (min'). If a metal ball is heated to 90°C and dropped into water that is held at constant value of Ta = 20°C, use Euler's Method to compute the ball's temperature after 140 seconds if k = 0.25 min -'. Assume a step size of h = 20 seconds.
