In temperature measurement, "positive" and "negative" typically refer to the sign of the value on the Celsius or Fahrenheit scales. Positive temperatures indicate warmth above the freezing point of water (0°C or 32°F), while negative temperatures indicate cold below that point. In the context of thermodynamics, positive values can signify heat flow into a system, whereas negative values might indicate heat flow out of a system. This distinction is crucial in various scientific and engineering applications.
