Q1/A mercury thermometer having a time constant of (180 s) is initially at (400°C), it is immersed in a bath of (120°C) at t=0, derive a formula to determine the indicated temperature at (t =1.2 min) and (t =2.3 min). Also, if the thermometer is read a temperature at (t =3.5 min), and then is removed from the bath and return to the initial bath, determine what will be the temperature reading at (t=5 min)?
