Changes in States

05 Feb Changes in States

Chemistry is a very interesting subject. It deals with a lot of things that we see around our surrounding and it has a lot of scopes and professions to offer. But it has a lot of critical topics within it. These topics should be taught with extensive care and guidance without it students will face difficulties to understand the subject and will fail to score good marks. Keeping that in mind Miracle Learning Centre has introduced a level chemistry tuition, o level chemistry tuition and jc chemistry tuition for the students of Singapore. Our classes are filled with fun games and activities which help students to learn better. Chemistry tuition class in Miracle Learning Centre is fun and enriching. You will learn about the different aspects of Science and how to learn study skills too. If you do not like or understand science, you must definitely attend the chemistry tuition class at Miracle Learning Centre to arouse and reignite your interest. Let us learn about the Changes in States in this science tuition lesson.

Almost every substance can exist as a solid, a liquid, or a gas. These are the three common states of matter. Whether a substance is in solid, liquid or gaseous state it depends on its temperature and the pressure placed on it.

There are different methods where the states can be changed. Some of the examples are melting, condensation and sublimation. Melting is when a solid is heated, the particles gain energy and vibrate faster and faster. Eventually, the particles are able to overcome the attractive forces that hold them together in their fixed positions and particles are free to move about in the liquid state.

Condensation is when a gas is cooled; the particles move slower and the mutual attractive forces become stronger. Eventually, the particles are arranged closely together but able to move about in the liquid. Sublimation is a process of changing from a solid to a gaseous state without melting. For example, heating the black solid iodine changes to violet-iodine gas or heating the white solid ammonium chloride changes to white fume of gaseous ammonium chloride.

Miracle Learning Centre would like to bring you more facts on chemistry tuition concepts and experiments. We hope you have understood this chemistry tuition lesson. Science tuition lessons are created to help students excel and we believe “You are a MIRACLE!” and you can do it too.
