Temperature is measured by which instrument?
Answer and explanation
Correct answer: Thermometer
Temperature tells us how hot or cold something is. It is measured with a thermometer. A thermometer contains a material or sensor that responds to changes in temperature, and its scale allows the reading to be recorded. Common temperature scales include Celsius and Fahrenheit, while scientific work also uses kelvin. Different thermometers may be designed for air, liquids, the human body, or laboratory experiments, but their basic function is the same: measuring temperature rather than pressure, rainfall, or direction.
Option B is correct because a thermometer measures temperature. Option A is incorrect because a rain gauge measures rainfall. Option C is incorrect because a barometer measures air pressure. Option D is incorrect because a compass shows direction. Remembering the measured element alongside the instrument prevents confusion: temperature–thermometer, air pressure–barometer, and rainfall–rain gauge. Thus, the answer follows directly from the instrument’s purpose.
