Question: A thermometer with first-order time constant = 0.1 min and gain = 1.0 is placed in a temperature bath (25 C). After the thermometer

A thermometer with first-order time constant = 0.1 min and gain = 1.0 is placed in a temperature bath (25C). After the thermometer comes to equilibrium with the bath, the temperature of the bath is increased linearly at a rate of 1 /min. 

(a) What is the difference between the measured temperature Tm and the bath temperature T at t = 0.1 min and t = 1.0 min after the change in temperature?
(b) What is the maximum deviation between Tm (t) and T (t)? When does it occur? 

(c) Plot both T(t) and Tm(t) to 3 mins. For large values of t, determine the time lag between Tm and T.
