Difficulty: EasyTemperature Scales and Thermometric Properties

Match each type of thermometer with its corresponding physical thermometric property.

  • Liquid-in-glass thermometerChange in length or volume of a liquid column
  • Constant-volume gas thermometerChange in pressure of a gas
  • Resistance thermometerChange in electrical resistance
  • ThermocoupleElectromotive force (e.m.f.) produced across junctions

Answer

Liquid-in-glass thermometer matches change in length or volume of a liquid column; Constant-volume gas thermometer matches change in pressure of a gas; Resistance thermometer matches change in electrical resistance; Thermocouple matches electromotive force (e.m.f.) produced across junctions.
Each thermometer is accurately matched to the physical property that undergoes a measurable change as temperature varies.

Step-by-Step Solution

1
Identify the defining physical property that varies with temperature for each instrument.
Each thermometer operates on a distinct physical property that changes predictably when heated or cooled.
Thermometric properties must be reproducible and continuously measurable across a temperature range.
2
Pair each instrument with its specific thermometric property.
Liquid-in-glass pairs with liquid column expansion/length; constant-volume gas thermometer pairs with gas pressure; resistance thermometer pairs with electrical resistance; thermocouple pairs with thermoelectric e.m.f.
These pairs represent standard physical principles used in thermometry.
