QUESTION 2 (Temperature Measurement) 1. Explain the mechanism of thermometer. 2. Explain the mechanism of thermocouple with schematic diagram. 3. Explain the mechanism of RTD. 4. Explain the mechanism of Thermistor using conductor and semiconductor. 5. Compare the application of thermocouple, thermistor, and RTD. 6. Explain the mechanism of two most common dial thermometers temperature sensor. 7. What are the advantages and disadvantages of both gas and bimetal temperature dial gauge. 8. Explain the fundamental difference between resistance thermometer and thermocouple. 9. A Thermocouple has linear calibration between \( 0^{\circ} \mathrm{C} \) and \( 500^{\circ} \mathrm{C} \) with emf at maximum temperature equal to \( 31.5 \mathrm{mV} \). The cold junction temperature is \( 25^{\circ} \mathrm{C} \). If the indicated emf is \( 10 \mathrm{mV} \), determine the temperature of the hot junction.
