Discussion Overview

The discussion revolves around the concept of temperature, specifically its definition and implications at the atomic level. Participants explore both the macroscopic and microscopic interpretations of temperature, as well as the effects of heating on substances.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants question the simplistic definition of temperature as merely a measure of coldness or hotness, seeking deeper understanding of atomic interactions during heating.
  • One participant suggests that temperature can be understood as a macroscopic property of large collections of molecules, where heat energy flows from higher to lower temperature collections.
  • Another participant notes that the temperature of a collection is related to the average energy per microscopic degree of freedom of the component molecules.
  • Some participants emphasize the importance of engaging with educational materials, such as Resnick and Halliday, to grasp the mathematical development of thermodynamics.
  • There is a mention that increasing the temperature of an ideal gas results in an increase in the average kinetic energy per molecule.

Areas of Agreement / Disagreement

Participants express differing views on the adequacy of standard definitions of temperature and the depth of understanding required to grasp its implications at the atomic level. No consensus is reached on a singular definition or explanation.

Contextual Notes

Some statements rely on assumptions about the definitions of temperature and the behavior of gases, which may not be universally accepted. The discussion reflects varying levels of familiarity with thermodynamic principles.

What is temperature?
The simple definition I get in books is that it is the measure of coldness or hotness,but what in real it is at the atomic level what does happens to the atoms when we we work on substance by heating.

There are much better explanations than this.

Where have you looked?

I have seen it and resnick halliday and the study material I got from my institute.

It is a macroscopic property of large collections of molecules. It has the property that if two such collections are put in contact passively, heat energy will flow from the one with a higher temperature to the one with the lower.

It turns out that for most commonly encountered situations, the temperature of a collection is given (up to a constant scaling factor) by the average energy per microscopic degree of freedom of the component molecules in that collection.

Post what you asked here mentioning atomic level in a Google search, science daily / and quora will give you some answers. I am not allowed to just give you the answer. Getting used to streamlining your searches, key words and targeting the best sites is more important then just getting the answer.

That's not what they say at all. They relate the mathematical development of thermodynamics to our everyday experience.

If you want to understand physics, you need to put more effort in.

For starters think of it as the thing you measure with a thermometer. That's enough to get you started and then you can refine the definition further as you develop your understanding.

but what in real it is at the atomic level what does happens to the atoms when we we work on substance by heating.

When you increase the temperature of an ideal gas you increase the average kinetic energy per molecule.
