Q2. A thermometer having a time constant of 0.1 min is set at a steady state temperature of 90 deg F at time t = 0. Then the thermometer is placed in water path maintained at 100 deg F. Determine the time needed for the thermometer to read 98 deg F.

Step 1
First, we need to understand the concept of time constant. The time constant (τ) of a thermometer is the time it takes for the thermometer to reach 63.2% of the difference between its initial temperature and the final temperature. In this case, the time constant Show more…

A thermometer reading $72^{\circ} \mathrm{F}$ is placed in a refrigerator where the temperature is a constant $38^{\circ} \mathrm{F}$ (a) If the thermometer reads $60^{\circ} \mathrm{F}$ after 2 minutes, what will it read after 7 minutes? (b) How long will it take before the thermometer reads $39^{\circ} \mathrm{F}^{-} ?$ (c) Determine the time needed to elapse before the thermometer reads $45^{\circ} \mathrm{F}$. (d) What do you notice about the temperature as time passes?
