What instrument is used to measure Temperature?

Temperature is how hot or cold something is, and the instrument that tells you that is a thermometer. A thermometer works by using a material that changes in a predictable way as temperature changes. In a traditional liquid-in-glass thermometer, the liquid expands when it gets warmer, rising higher in the tube to indicate the temperature on a scale. Modern thermometers use electronic sensors or infrared detection, but the idea remains the same: a measurable change in response to heat provides the temperature reading. Other instruments measure different properties: a barometer measures atmospheric pressure, a hydrometer gauges the density or specific gravity of a liquid, and an anemometer measures wind speed.
