Make the connection secure d. None of the above 19. What is the basis of how thermocouples work a. Change of resistance because of temperature difference b. Change of voltage because of temperature difference c. Infra-red radiation of the object d. Heat conduction 20. A thermocouple is held initially at Temperature T_1 = 100 deg C and at time is exposed to stationary air at romm temperature. What happens to the temperature measured a. Increases based on free convection b. Decreases based on free convection c. Increases based on forced convection d. Decreases based on forced convection 21. What temperature s

Solution

15 - d

16 - c = 1000 x 10^-6 x 100% = 0.1%

17 - b

18 - a
