"absolute zero"
or 0 degrees Kelvin.
The temperature scale that places zero at the point where all atomic and molecular motion ceases is called the Kelvin scale. On the Kelvin scale, this point is defined as absolute zero, which is equivalent to 0 Kelvin (0K).
The zero point on the Kelvin scale is called absolute zero. At this temperature, all molecular motion ceases, and it is equal to -273.15 degrees Celsius.
Zero Kelvin represents the theoretical point at which all molecular motion ceases, making it the lowest possible temperature in the universe. At zero Kelvin, all particles would be at their lowest energy state and be completely still.
The point where particles in a medium stay when there are no disturbances is called the equilibrium position. At this point, the particles are at rest and do not experience any displacement. When a disturbance occurs, the particles oscillate around their equilibrium position.
Absolute zero is the theoretical lowest temperature because it is the point at which the particles that make up matter have minimal energy and motion. At this temperature (-273.15 degrees Celsius or 0 Kelvin), all thermal activity ceases, making it impossible to further lower the temperature.

Molecules are not in random motion when a substance is at absolute zero, the lowest possible temperature at which molecular motion ceases. At this point, molecular movement only exists due to the zero-point energy, preventing complete immobilization.
The zero point on the Kelvin scale is called absolute zero. At this temperature, all molecular motion ceases, and it is equal to -273.15 degrees Celsius.

The equator
No, molecular motion actually increases when water is boiling. When water reaches its boiling point, the molecules absorb enough heat energy to break free from the liquid phase and transition into the gaseous phase, leading to increased molecular motion.
Absolute zero is the theoretical temperature at which all atomic motion stops. However, this temperature is unattainable, because it represents a complete lack of energy within particles of matter. Even in deep space, this temperature cannot be reached so, like the speed of light, it is a scientific limit which can only be approached. On the Kelvin scale it's 0, on the Celsius scale it's -273.16.

The scientific measurement for temperature is typically done in either degrees Celsius (°C) or Kelvin (K). Degrees Celsius is based on the freezing and boiling points of water, while Kelvin is based on absolute zero, the theoretical point at which all molecular motion stops.
Temperature is measured at 0 Kelvin (-273 degrees Celsius) because it is the point at which all molecular motion stops. This point is known as absolute zero and serves as the basis for the Kelvin temperature scale.
