Write the governing equation for the thermometer.

 ...... (1)

Here, surrounding temperature is  , steady state temperature is  , initial temperature is, time is t, and average time constant for the thermometer is  .

Calculate the average time constant for the thermometer  .

 ...... (2)

Here, time constant at  is  and time constant at  is  .
