Molecular Energy With Relation to Number of Molecules

Click For Summary

Discussion Overview

The discussion revolves around the distribution of molecular energies in a gas at different temperatures, specifically comparing the distributions at 500 K and 300 K. Participants are exploring how temperature affects energy distribution and are attempting to identify the correct representation of this relationship through graphical curves.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant expresses uncertainty about how to determine which solid-line curve accurately represents the distribution of molecular energies at 500 K, noting that higher temperatures correlate with higher energy.
  • Another participant inquires about the areas under the curves, suggesting a potential link to total energy.
  • Further questions arise regarding the y-axis of the graph, with one participant clarifying that it represents the number of molecules.

Areas of Agreement / Disagreement

The discussion remains unresolved, with participants asking questions and expressing uncertainty rather than reaching a consensus on the correct curve representation.

Contextual Notes

Participants have not provided specific equations or definitions related to the curves, and assumptions about the relationship between temperature and energy distribution are not fully articulated.

Homework Statement


Which solid-line curve most accurately represents the distribution of molecular energies in a gas at 500 K if the dotted-line curve represents the corresponding distribution for the same gas at 300 K?

The Attempt at a Solution


Not sure how this works.
Higher the temperature, more the energy, so that rules out (D)
But that still leaves options A,B and C
