[11 Marks] Q1(c) A temperature measurement device is used to record temperature during processing of liquid compounds. Initially the thermocouple is at equilibrium in air at 20 °C when it is immediately placed in a vessel of liquid at 60 °C for 3 minutes. After this it is removed and left in air for a further minute. Calculate the error in measurement at 10, 30, 180(when still in water) and 200 seconds. Assume the time constant in air is 10 seconds and in the liquid is 5 seconds. To= 20
