# At what temperature would molecular motion nearly cease?

## At what temperature would molecular motion nearly cease?

The Kelvin Scale It is based on molecular motion, with the temperature of 0K, also known as absolute zero, being the point where all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15K, while the boiling point is 373.15K.

At what the lowest possible temperature all molecular movement stops?

-273.15° C.
A temperature scale whose zero point is absolute zero, the temperature of 0 entropy at which all molecular motion stops, -273.15° C. The size of a degree Kelvin is the same as the size of a degree Celsius.

### What is the lowest possible temperature possible called?

Absolute zero
Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach.

At what temperature does all molecular motion stop and no heat energy remains what is this called?

0 degrees Kelvin
All molecular motion stops at 0 degrees Kelvin or -273.15 degrees Celsius.

#### What temp is absolute zero?

At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.

At what temperature do molecules stop moving?

zero kelvin
At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.

## Who discovered absolute zero?

William Thomson
In 1848, the Scottish-Irish physicist William Thomson, better known as Lord Kelvin, extended Amontons’ work, developing what he called an “absolute” temperature scale that would apply to all substances. He set absolute zero as 0 on his scale, getting rid of the unwieldy negative numbers.

Can an atom stop moving?

At the physically impossible-to-reach temperature of zero kelvin, or minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius), atoms would stop moving. As such, nothing can be colder than absolute zero on the Kelvin scale.

### Why do particles never stop moving?

Molecules, even at absolute zero, always have energy. The vibrational zero- point energy of the molecule still corresponds to movement, so even though the molecule is at absolute zero, it is still moving.

Why can’t temperature go below absolute zero?

#### What is the temperature at which all molecular motion ceases?

The lowest possible temperature (which cannot actually be reached) is called absolute zero. At this temperature, there would be zero molecular motion.On the various temperature scales, it would be 0 kelvins, -273.15° Celsius, or -459.67° Fahrenheit What is the temperature at which all atomic and molecular kinetic motion ceases?

When does the motion of molecules stop in absolute zero?

Temperature is equivalent to molecular motion; if the temperature is absolute zero, so is the motion. When does all motion of molecules stop? When the temperature reached absolute zero (0 Kelvin or -273 Celsius), all molecular motion ceases. What temperature centigrade does all molecular motion stop?

## Which is the lowest possible temperature in the universe?

The lowest possible temperature, or absolute zero as it is called, is -459.67°F (-273.15°C). It is also called 0 kelvin, a scale with increments equivalent to degrees of Celsius, but which uses absolute zero rather than water’s freezing point as its starting point. This is the point at which all atomic motion ceases.

Which is the absolute zero temperature on the Kelvin scale?

The temperature is called absolute zeroand is approximately -273.15 °C, or zero on the Kelvin scale. The Kelvin scale is named after the Belfast-born engineer and physicist William Thomson, 1st Baron Kelvin (1824-1907), who wrote of the need for an “absolute thermometric scale”.
