Because pressures and temperatures can vary over very wide ranges, it is common practice to draw phase diagrams with non-linear or distorted coordinates. This enables us to express a lot of information in a compact way and to visualize changes that could not be represented on a linearly-scaled plot.
16 de ago. de 2023 · Lesson 1.3 Interactive. Point out that when the thermometer is heated, the molecules move faster, get slightly further apart, and move up the tube. When the thermometer is cooled, the molecules move more slowly, get closer together, and move down the tube. Help students realize that the attractions the molecules in the thermometer have for each ...

SectionTitleSection I4-01Section I4-11Section I4-12Section I4-13Lesson Explainer: Changes of State. In this explainer, we will learn how to describe and explain changes of state and identify these changes through diagrams and heating curves. All molecules move, but they do not all move at the same speed.
Changes of state are examples of phase changes, or phase transitions. All phase changes are accompanied by changes in the energy of a system. Changes from a more-ordered state to a less-ordered state (such as a liquid to a gas) are endothermic.
