At what tempurature is there no heat?

Answer 1

Zero Kelvin.

Absolute zero refers to the temperature of a system that is thermically inert. Such a (theoretical) system neither emits nor absorbs heat energy. The Absolute zero temperature is known to be 0 K (-273.15 C). While it is possible to cool any substance to near Absolute Zero, it can never actually be achieved.

Absolute zero is the point at which particles have a minimum energy, determined by quantum mechanical effects, which is called the zero-point energy.

By international agreement, absolute zero is defined as precisely 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale, and -273.15°C on the Celsius scale.[1] Absolute zero is also precisely equivalent to 0 °R on the Rankine scale (also a thermodynamic temperature scale), and –459.67 °F on the Fahrenheit scale.

Whilst scientists cannot fully achieve a state of “zero” heat energy in a substance, they have made great advancements in achieving temperatures ever closer to absolute zero (where matter exhibits odd quantum effects). In 1994, the NIST achieved a record cold temperature of 700 nK (billionths of a kelvin). In 2003, researchers at MIT eclipsed this with a new record of 450 pK (0.45 nK).

Answer 2

In addition to the excellent explanation of the other answerer, the Second Law of Thermodynamics leads to the conclusion that the most efficient use of heat would occur if the heat was discharged at absolute zero. There are practical problems involved in attempting to do this.

Answer 3

Absolute zero (or -273 degrees celcius).
This is when the vibrational energy of an atom ceases and therefore has no energy.
However, it is impossible to reach absolute zero due to the 3rd law of thermodynamics.

Answer 4

Zero kelvin
also mknown as -273 degrees C or -273.15 to be precise
aka absolute zero
