Chemistry GCSE Review - States of Matter, Particles, Atoms, Elements, Compounds and Mixtures

Frage 1 von 10

10

Physical changes change a substance from one ❌ to another. This does not change the particles in the substance themselves, just their ❌ and level of energy.
If a substance is ❌, heating it enough causes it to ❌, forming a liquid. Conversely, ❌ a liquid enough causes it to freeze. From the ❌ state, heating further causes evaporation and eventually ❌, causing it to change into a ❌. The process of ❌ occurs when a gas is cooled enough for it to become a liquid.
Some substances do not pass through the liquid state, and instead pass straight from solid to gas and back again. The passing from solid to gas after being heated is called ❌, with the passing back known as deposition.

Gases have ( a very weak, no, a very strong, an average ) force of attraction between particles. These particles are free to move and are far apart. They have no definite shape or ( volume, mass, molecular formula ), expanding to fill a container they are in. These particles move constantly ( in straight lines, in curves, by quantum leaping ), with random motion. The hotter the gas gets, the ( faster, slower, less ) the particles move. Two things can happen to the gas when it is heated: either it expands, or the ( pressure, boiling point, number of particles ) increases.

Solids have a shape and volume and, although the particles do not move constantly, they vibrate about their positions. The the solid becomes the more these particles vibrate (causing the solid to expand).

the sudden movement of particles through a fluid from places with a high concentration to places with a low concentration.
the gradual movement of particles through a fluid from places with a low concentration to places with a high concentration.
the sudden movement of particles through a fluid from places with a low concentration to places with a high concentration.

Elements are substances that consist of ( only one, one or more, only two, two or more ) type of atom. Many everyday substances are elements, including ( nitrogen, ammonium, ammonia ), oxygen, ( iron, pyrite, steel ), gold, ( copper, chalcopyrite, copper chloride ) and aluminium. If two atoms have the same number of ( protons, protons and neutrons, neutrons ), they are of the same element.
Compounds are comprised of ( two or more, only one, more than one, only two ) different elements chemically ( bonded, attracted, combined ) in some way. There are three kinds of bonding, called ( covalent, ionic and metallic, covalent, stringent and additive, covalent, giant and ionic, constant, ionic and metallic, covalent, giant and molecular ). Examples of chemical compounds include carbon dioxide (( CO2, CO, C2O, C2O2 )), water (( H2O, H2O2, HO, HO2 )), ethane (( C2H6, C2H4, C6H2, C2H2 )) and sulphuric acid (( H2SO4, H2SO3, H2SO2, H2SO )).
The constituent parts in a mixture, unlike in a compound, are ( not chemically bonded, orbiting each other, magnetically attracted to each other ). These constituent parts also do not just have to be elements - they can also be compounds themselves. For example, air is a mixture of gases including carbon dioxide (CO2), oxygen (( O2, O, O3, OO )), nitrogen (( N2, N, NN, N3 )), argon (( Ar, Ar2, ArAr, Ar3 )) and water vapour (H2O). Another example is crude oil, a mixture of different ( fractions, gases, distillations ), which are themselves mixtures of various ( hydrocarbons, carbonates, hydroxides, carbohydrates ).
