Question

What is the temperature of absolute zero measured in °c?

a. –173°c
b. –373°c
c.–73°c
d. –273°c

Answer 1

Absolute zero is –273.15°C, which is the theoretical temperature where all molecular motion stops, and it corresponds to 0 K on the Kelvin scale.

Step-by-step explanation:

The temperature of absolute zero measured in degrees Celsius is –273.15°C. Absolute zero is the point at which all molecular motion ceases and it represents the lowest possible temperature that can theoretically be achieved. In the Kelvin scale, this temperature is represented as 0 K. Although absolute zero is a theoretical limit and gases tend to liquefy and freeze before reaching it, this temperature is an important concept in physics and thermodynamics. For practical purposes, when considering significant figures commonly used in classroom settings, the answer can be rounded to –273°C.
