It is the fifth state of matter. Albert Einstein and Satyendra Nath Bose predicted this state of matter, that is why it is known as the Bose-Einstein Condensate (BEC). Condensate atoms are super cool and super unexcited. Example: superfluids. (a) What are the two ways in which the phy...
Chemistry is the study of matter and how it changes. Matter is everything that has mass and takes up space, like the air we breathe, the water we drink, and the objects we use every day. Chemistry helps us understand what things are made of and how they interact with each other. For...

Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B) ,C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single...
Matter can exist in various phases: solid, liquid, gas, or plasma. Most substances can transition between these phases based on the amount of heat the material absorbs (or loses). There are additional states or phases of matter, including Bose-Einstein condensates, fermionic condensates, and qua...
Definition of Chemical Properties of Matter As you look at the things around you, it is easy to see many of their physical properties such as color, shape, and size. Some properties of a substance are not as obvious, unless the substance has changed composition as a result of a chemical ...

5 States of Matter Solid- particles are tightly packed, usually in a regular pattern. particles vibrate (jiggle) but generally do not move from place to place. Liquid- particles are close together with no regular arrangement. Particles vibrate, move about, and slide past each other. Gas- part...
Chemistry is all about states of matter, including liquids, solids, and gases. It is all about how different materials are put together and made up of atoms and molecules. Additionally, chemistry is how these materials act under different conditions. Slime is a non-Newtonian fluid. A non-...
Liquids exist in a relatively small part of the enormous range of temperatures and pressures existing in the universe. Nevertheless, they are of vital importance for physics and chemistry, for technology, and for life itself. A century of effort since the pioneering work of van der Waals has ...
