Kelvin scale — starting point?
Begins at absolute zero (0 K).
Temperature conversion — formula?
K = °C + 273.15.
Molecular vibration — role?
Indicates thermal energy and temperature.
Thermocouple — principle?
Uses Seebeck effect to generate voltage.
Thermistor — resistance change?
Resistance decreases as temperature increases in NTC types.
Shape change measurement — method?
Bending of bimetallic strips due to thermal expansion.
Seebeck effect — phenomenon?
Voltage generated by temperature difference across conductors.
Absolute zero — significance?
Point where molecular motion ceases.
Thermocouple voltage — proportional to?
Temperature difference between junctions.
Thermistor — key characteristic?
Resistance varies predictably with temperature.
