Absolute zero is

Absolute zero is

• A. -460 degrees F
• B. -459.67 degrees F
• C. 0 degrees F
• D. -100 degrees F

Answer: (A)

Absolute zero means the lowest possible temperature, where particle motion is as close to stopping as physics allows. It’s defined as 0 kelvin. Converting to other scales helps see the scale: 0 K is -273.15 C, which is -459.67 F. In many contexts this is rounded to about -460 F, so that rounding matches the idea that absolute zero is an extreme negative temperature on the Fahrenheit scale. The important thing to grasp is why this value is so far below freezing: it represents the point at which thermal energy is essentially minimized, not just a particular degree on the Fahrenheit scale. The other numbers are simply not close to this fundamental limit.
