Which type of thermometer is used for measuring the internal temperature of ice?
Laboratory thermometer
The correct answer is Laboratory thermometer.
Laboratory thermometers are designed for a wide range of temperature measurements, including very low temperatures like that of ice. They are typically more accurate and durable than clinical thermometers, and their temperature range extends far beyond body temperature. Infrared thermometers measure surface temperature, not internal temperature, and would not be suitable for this purpose. Digital thermometers, while versatile, often lack the precision and temperature range needed for such precise measurements in low temperature ranges like that found within a block of ice. Clinical thermometers are specifically designed for measuring human body temperature and have a limited temperature range.
Therefore, a laboratory thermometer is the most appropriate instrument for accurately measuring the internal temperature of ice.
