A thermometer follows first-order dynamics with a time constant of 0.2 min. It is placed in a temperature bath at 100°C and is allowed to reach steady state. It is suddenly transferred to another bath at 150°C at time t = 0 and is left there for 0.2 min. It is immediately returned to the original bath at 100°C. Calculate it's reading at, (i). t = 0.1 min (ii). t = 0.4 min
