05 Feb States of Matter
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. Let us learn about the States of Matter in this Chemistry tuition lesson.
States of Matter
Matter can exist in three physical states namely solid, liquid or gas. Solid and liquid have fixed volume while gas has no fixed volume.
Properties of Each State
In addition, a solid has a fixed shape and cannot be compressed while liquid and gas has no fixed shape and takes the shape of its container. The liquid can be compressed a little while gas can be easily compressed.
Changing States of Matter
The three states can be changed from different states to states through different processes.
Sublimation
Solid can be changed to gas through the process of sublimation. For example, when heating the black solid iodine, it will change to violet-iodine gas.
Melting and Boiling
Furthermore, when solid changes to liquid, the process is called melting and boiling or evaporating is the process of changing liquid to gas.
Condensation and Freezing
In addition, gas can be converted to liquid through the process of condensation and when liquid converts to solid, it is called freezing.
Cooling
When gas is converted to solid directly it is called cooling.But recently two more states have been discovered.
Plasma
Plasma is not a common state of the matter here on Earth, but maybe the most common state of matter in the universe. It consists of highly charged particles with extremely high kinetic energy. The noble gases are often used to make glowing signs by using electricity to ionize them to the plasma state.
Bose-Einstein condensates
In 1995, technology enables scientists to create a new state of matter, the Bose-Einstein condensate (BEC). Using a combination of lasers and magnets scientists cooled a sample of rubidium to within a few degrees of absolute zero.
At this extremely low temperature, molecular motion comes very close to stopping altogether. Since there is almost no kinetic energy being transferred from one atom to another, the atoms begin to clump together.
There are no longer thousands of separate atoms, just one “super atom”. A BEC is used to study quantum mechanics on a macroscopic level.

FAQS:
What are the 7 states of matter?
Yes, there are seven states of matter. There are three major states of matter on Earth that most people are familiar with. These are solid, liquid, and gas. Aside from plasma, Bose-Einstein condensates, quark-gluon plasmas, and degenerate matter are also state of matter.
