Unit 9 · Thermodynamics and Electrochemistry

Chapter 9.1

Entropy: How Matter and Energy Spread Out

Ice melts in a warm room without anyone pushing it, and a gas fills a vacuum on its own. Both are the universe drifting toward the arrangements that can happen the most ways.

in preparation · lesson 41 of 45

By the end

  1. 01Predict the sign and relative size of an entropy change for a chemical or physical process
  2. 02Explain entropy as matter and energy spreading out, including its rise with temperature
  3. 03Compute a standard entropy change from absolute molar entropies
