Final answer:
A meat thermometer is used to measure the temperature of foods, especially meats, to ensure they are cooked to the desired and safe temperature. It provides readings in both Fahrenheit and Celsius and functions based on temperature-induced changes in material volume or state. The correct option is C).
Step-by-step explanation:
A meat thermometer is a special type of thermometer used to measure the temperature of many foods. By inserting a meat thermometer into a piece of meat while cooking, one can ensure that the meat is cooked to the desired temperature, which is important both for culinary and food safety reasons.
This type of thermometer can usually be read instantly or after a short period and often has both Fahrenheit (expressed as °F) and Celsius (expressed as °C) scales printed on it so responses can be interpreted according to the recipe being used or personal preference.
Thermometers in general function based on materials that expand or contract with temperature changes, with liquid-based thermometers like mercury or alcohol relying on reservoirs that show a change in liquid column length corresponding to temperature fluctuations.
In the context of kitchen use, meat thermometers provide an easy and accurate reading that ensures food safety and optimal culinary results. Option C) is the correct one.
