The time response of a liquid-in-glass thermometer was tested by plunging it into a

container of boiling water and recording the temperature at intervals of 10 seconds

over 2 minutes. The thermometer was initially at 0C and the following readings

were recorded:

Time (seconds) 0 10 20 30 40 50 60 70 80 90 100 110 120

Temp (C) 0 31 52 67 77 84 89 92 95 96 97 98 99

Draw a graph of the output readings against time. Using this graph, estimate the time

constant of the thermometer.
