Vaporization 17. 16. C. TRUE OR FALSE 18. Gases have an indefinite shape and a definite volume. 19. The motion/speed of the particles increases as the temperature of the particle is decreases. 20. Because the shape of a solid never changes, the particles of solid do not move. _21. Particles can stick together because of the intermolecular forces between the particles. _22. It is possible to heat pure water at the temperature of 127°C. 23. Energy is either absorbed (Exothermic) or released (Endothermic) during a phase change. _24. The temperature of a substance changes during a phase change (melting/boiling). _25. The freezing point and the melting point of a substance are the same temperature.

Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.
