Chemical Engineering

4. A state of matter characterized by particles arranged such that their shape and volume are relatively stable.
6. A temperature scale based on 0o for the freezing point of water and 100o for the boiling point of water.
8. The basic building block of matter, consisting of protons, neutrons, and electrons. This is the smallest unit of matter that forms a chemical element and cannot be divided using any chemical means. Every solid, liquid, gas, and plasma consists of neutral or ionized these.
9. The particle in the atomic nucleus with a mass = 1 and charge = 0.
12. A component of an atomic nucleus with a mass defined as 1 and a charge of +1.
17. The change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization.
18. Means combining lighter atomic nuclei to form a heavier nucleus.
19. The ability of a substance, usually metal, to be deformed or moulded into a different shape is referred to as this.
21. The process through which a substance changes from a liquid to a solid.

1. Positively charged center of the atom consisting of protons and neutrons.
2. Are subatomic particles that hold an elementary charge of magnitude -1.
3. A chemical substance that cannot be broken down into other substances by chemical reactions.
5. In chemistry, dissolving is the process of causing a solute to pass into a solution.
7. An ionic compound that contains a cation and an anion. It is present in seawater and essential for animal life.
10. The phase change from the liquid to gas phase.
11. A gas that can be produced by any substance when it is heated to a temperature of 100 degrees Celsius or higher.
13. A state of matter consisting of particles that have neither a defined volume nor defined shape.
14. Any substance that has mass and takes up space by having volume.
15. A property that reflects the quantity of matter within a sample.
16. An atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge.
20. The particles in it are free to flow, so while a it has a definite volume, it does not have a definite shape.
