There are four main changes of state: melting, freezing, evaporating and condensing. Did you know? Liquids do not have to be heated to their boiling point to evaporate - evaporation can take...
Learn what the changes of state are and how matter can change from a gas to a liquid. This KS3 Chemistry guide helps you revise all of this and more.
Explore the interactive simulation of matter states and learn about phase changes, temperature effects, and atomic interactions.
12 de abr. de 2023 · 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.
20 de ago. de 2020 · Everyday we take advantage of changes between the gas, liquid, and solid states to cool a drink with ice cubes (solid to liquid), cool our bodies by perspiration (liquid to gas), and cool food inside a refrigerator (gas to liquid and vice versa).
13 de nov. de 2022 · In this unit, we will learn what common factors govern the preferred state of matter under a particular set of conditions, and we will examine the way in which one phase gives way to another when these conditions change.
