Final answer:
A temperature of -2°F is warmer than -6°F by 4 degrees on the Fahrenheit scale.
Step-by-step explanation:
A temperature of -2°F is warmer than a temperature of -6°F. Even though both temperatures are below the freezing point of water, the temperature scale on the Fahrenheit scale, being an interval scale, shows that -2°F is four degrees warmer than -6°F.
In temperature comparisons, it's important to understand that a higher number on the Fahrenheit scale indicates a warmer temperature, and a lower number indicates a colder temperature, regardless of whether the temperatures are above or below zero. This applies to other temperature contexts as well, like comparing the energy required to maintain different indoor temperatures or the change in heat energy during phase transitions in substances like water and ice.
