Chapter U3.5, Problem 8E

Interpretation Introduction

Interpretation:

The highest temperature which can be reached by any substance must be explained with reasoning.

Concept introduction:

A hot object releases heat energy to cold object.

Answer to Problem 8E

The highest possible temperature which can be reached by any substance is $1.42\times {10}^{33}$ °C.

Explanation of Solution

Practically scientists have tried to reach higher temperature which is also known as Planck temperature.

Theoretical calculations were done using the concept of conventional physics. The calculation showed that highest possible temperature is approximately $1.42\times {10}^{33}$ °C. Above this temperature, particle energy becomes too large resulting in strong gravitational forces between those particles as other fundamental forces. The big bang theory assumes that during the creation of the universe, this temperature was created for avery short time. Thus, above this temperature,there is no theory that can work.
