What is the temperature of absolute zero?

Absolute zero is defined as the lowest possible temperature, where all classical motion of particles comes to a complete stop. It is measured as 0 Kelvin (K), which corresponds to -273.15 degrees Celsius (°C).

In the Fahrenheit scale, absolute zero is -459.67°F. Among the provided choices, -460°F is the closest approximation of absolute zero in Fahrenheit and accurately reflects the concept that temperature can go lower than the freezing point of water. Therefore, selecting -460°F aligns with the scientific understanding of absolute zero.

It's important to note that the other temperature options do not accurately represent absolute zero, either being significantly higher or not scientifically recognized as the point at which molecular motion ceases.
