When would an object stop emitting radiation when it reaches - 273 Calvin when it reaches zero Kelvin when it reaches zero Celsius it would never stop emitting radiation

Answer: when it reaches zero Kelvin

Explanation:

In this case, when we talk about radiation, we refer to thermal radiation, which is electromagnetic radiation that is generated by the thermal movement of charged particles in a body or object.

In this context, every body with a temperature greater than absolute zero (0 Kelvin) emits thermal radiation.

However, lowering the temperature decreases the movement and kinetic energy in the body's molecules, causing a decrease in the emitted radiation. Therefore, if a body reaches 0 K it would stop emitting radiation.
