What is the highest temperature which can be created on earth for a sufficiently long time?

Hint: The absolute scale of temperature on earth is the kelvin scale temperature. The temperature of a body depends on the energy entering and leaving a planet’s system. The temperature 250000 times the temperature of the sun can be created by humans.

Complete step-by-step solution:
The earth is the only planet which can support life. Because the earth surface is not so close or too far from the sun. Hence the earth has a moderate temperature. And this zone is called the Goldilocks zone. The most important factor that makes a planet habitable is the distance from the sun. Earth’s atmosphere also plays an important role in maintaining earth’s temperature. The earth’s internal temperature increases with increase in depth.
Therefore the highest temperature which can be created on earth for a sufficiently long time is 3000K.

Note: The absolute scale of temperature on earth is the kelvin scale temperature. Below this point the temperature is not possible. The scientist created temperature by the smashing of gold ions together which is at the speed of light. The hottest man-made temperature is reached in the large Hadron collider to form a quark gluon plasma.
