Question 1: Resistance thermometers, also called resistance temperature detectors or resistive thermal devices (RTDs), are temperature sensors that exploit the predictable change in ________ of some materials with changing temperature.
Electric currentElectrical resistanceElectrical impedanceElectrical conduction

Question 2: These sensors work up to 961.78 °C and are used in the SPRT’s that define ________
HeliumOxygenInternational Temperature Scale of 1990Hydrogen

Question 3: They are slowly replacing the use of ________ in many industrial applications below 600 °C, due to higher accuracy and repeatability.
CobaltOxygenIronThermocouple

Question 4: The application of the tendency of electrical conductors to increase their electrical resistance with rising temperature was first described by Sir William Siemens at the Bakerian Lecture of 1871 before the Royal Society of ________.
Great BritainEnglandScotlandUnited Kingdom

Question 5: ________ have a range of −180 to 2,320 °C (-292 to 4,208 °F),[1] so for extremely high temperatures they are the only contact temperature measurement choice.
