Temperature is the degree of ____ of the ambient air as measured by any suitable instrument.

The degree of hotness or coldness of the ambient air is indeed what temperature measures. This concept is essential in aviation and meteorology, especially when understanding how temperature can affect air density, aircraft performance, and overall weather patterns.

Temperature provides a quantitative measurement that indicates how warm or cool the air is, usually referenced in degrees Celsius or Fahrenheit. It influences other weather elements, such as humidity and pressure, and plays a crucial role in the formation of clouds and precipitation.

Understanding this definition is vital, as it helps in interpreting various weather reports and conditions that pilots and aeronautical professionals need to be aware of when planning flights or assessing potential weather-related impacts on aviation operations.
