A thermometer measures temperature by directly quantifying thermal energy.
Thermometers use a material\’s physical property that changes with temperature.
The length of a liquid column is a physical property used in some thermometers.
The electrical resistance of a material is never used in thermometers.
A thermocouple produces an electromotive force (e.m.f.) that is independent of temperature.
A fixed mass of gas at constant pressure can be used as a basis for a thermometer.
The density of a liquid is not a physical property used in thermometers.
Thermometers are usually calibrated at a single known temperature.
The melting and boiling points of water are commonly used as fixed points for calibration.
All thermometers will always agree on temperature measurements except at fixed points.
The expansion of a liquid in a liquid-in-glass thermometer is always linear with temperature.
The relationship between a physical property and temperature is always proportional.
The constant volume gas thermometer uses the expansion of gas to measure temperature.
The triple point of water is not used in calibrating thermometers.
The readings on a thermometer are always an exact measurement of the temperature of an object.
Calibration ensures that a thermometer’s readings are accurate only at the fixed points.
A thermocouple thermometer is more robust than a liquid-in-glass thermometer.
A thermistor has a linear change in resistance over a large temperature range.
A liquid-in-glass thermometer depends on a change in density of a liquid.
The thermodynamic scale is based on the property of a particular substance.
