Chemistry B vocab

6. continuous physical force exerted on or against an object by something in contact with it.
8. chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically, a corrosive or sour-tasting liquid of this kind.
9. law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.
11. liquid or gel that contains ions and can be decomposed by electrolysis, e.g., that present in a battery.
12. lower than 100% because the actual yield is often less than the theoretical value.
19. as much water or moisture as can be absorbed; thoroughly soaked.
20. heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
21. (an event or situation, typically one that is bad or undesirable) to happen suddenly, unexpectedly, or prematurely.
22. or assume the existence, fact, or truth of (something) as a basis for reasoning, discussion, or belief.
24. radioactive isotope.
25. emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.

1. law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
2. time taken for the radioactivity of a specified isotope to fall to half its original value
3. process or result of joining two or more things together to form a single entity.
4. (a liquid) thinner or weaker by adding water or another solvent to it.
5. not forming a homogeneous mixture when added together.
7. disconnection or separation of something from something else or the state of being disconnected.
10. fast-moving electron emitted by radioactive decay of substances. (The emission of beta particles was originally regarded as a ray.).
13. to solve.
14. atoms and/or molecules of a hotter object have greater kinetic energy than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion
15. nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
16. lowest part or edge of something, especially the part on which it rests or is supported.
17. a subatomic particle with the same mass as an electron and a numerically equal but positive charge.
18. able to be dissolved, especially in water.
23. hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.
