Temperature and Its Measurement
Physics · 50 practice questions
Concept of temperature; thermometric properties; calibration of thermometers; temperature scales — Celsius and Kelvin; types of thermometers; conversion from one scale to another.
- Identify thermometric properties used in different thermometers and calibrate thermometers.
- Differentiate between temperature scales (Celsius, Fahrenheit, Kelvin) and compare types of thermometers.
- Convert from one scale of temperature to another.
Try a few questions
- Practice question 1
A thermometer's range refers to the
- A.exact single temperature it was calibrated to measure
- B.physical length of the thermometer's glass tube
- C.time taken for the thermometer to reach a stable reading
- D.span of temperatures it is capable of accurately measuring, defined by its lower and upper limits
Show the answer
D. span of temperatures it is capable of accurately measuring, defined by its lower and upper limits
Range specifically describes the full span of usable temperatures the instrument can reliably measure.
- Practice question 2
A temperature of -10°C, converted to Kelvin, is
- A.283 K
- B.263 K
- C.10 K
- D.-283 K
Show the answer
B. 263 K
Kelvin = Celsius + 273 = -10 + 273 = 263 K.
- Practice question 3
A digital thermometer commonly uses a
- A.column of mercury to measure temperature by its expansion
- B.thermistor (a type of resistance thermometer) or thermocouple to measure temperature electronically
- C.column of coloured alcohol to measure temperature by its expansion
- D.bimetallic strip alone, with no electronic component involved
Show the answer
B. thermistor (a type of resistance thermometer) or thermocouple to measure temperature electronically
These electronic sensing components allow a digital thermometer to convert temperature directly into an electrical reading.
