Particles 1 of 25 A property is a ............... Characteristic 2 of 25 In ......, the particles have a fixed/regular arrangement. They are very closely packed and are strongly bonded, and they vibrate. Solids 3 of 25 In ......., the particles have a random arrangement. They are closely packed, but are weakly bonded and can swap places with each other. Liquids 4 of 25 In ......, they particles have a random arrangement. They are spread out and thus not bonded, and they have a random, fast motion.

Cooled 14 of 25 The scientific term for a substance increasing its volume. Expansion 15 of 25 The scientific term for a substance decreasing its volume. Contraction 16 of 25 The 3D space that a substance occupies. Volume 17 of 25 Some chemical reactions produce a gas. If the gas is made underwater, it is seen as 'fizzing' or 'bubbles''. The correct term is .............. Effervescence 18 of 25 A simple yet obvious change that indicated the presence of a chemical being tested for. Qualitative 19 of 25 It is the ........... of atoms in a substance particle that gives it its properties. Arrangement 20 of 25 When chemicals ....., reactant particles change into product particles. React 21 of 25 ....... measures how much mass there is in a fluid volume of material. Density 22 of 25 A ................. will alter the arrangement of the particles.
