1.2. A thermometer having first-order dynamics with a time constant of 1 min is placed in a temperature bath at 100F. After the thermometer reaches steady state, it is suddenly placed in a bath at 110F at t=0 and left there for 1min, after which it is immediately returned to the bath at 100F. Calculate the thermometer reading at t=0.5min and at t=2.0min
