Across
- 2. the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great
- 3. the spreading of something more widely
- 6. the quality of being hot; high temperature
- 7. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization
- 11. an educated guess
- 13. the state of not being definite or certain because you may want to change it later
- 16. the pressure exerted by the weight of the atmosphere
- 19. continuous physical force exerted on or against an object by something in contact with it
- 21. corresponding in size or amount to something else
- 23. the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
- 25. the way in which a substance, typically a liquid, holds together; thickness or viscosity
- 27. statements that link evidence back to reasons or claims
- 28. a substance which does not readily allow the passage of heat or sound
- 29. a statement in which a writer presents an assertion as truthful to substantiate an argument
Down
- 1. the degree of compactness of a substance
- 4. the quality or state of being natural
- 5. a fundamental principle of physics
- 8. if one variable increases the other will decrease, and if one variable decreases the other will increase
- 9. a temperature scale based on 0 o for the freezing point of water and 100 o for the boiling point of water
- 10. an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude
- 12. the lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal. It is zero on the Kelvin scale, equivalent to –273.15°C or –459.67°F.
- 14. energy energy associated with microscopic forms of energy
- 15. a coherent, typically large body of matter with no definite shape.
- 17. the fact of occurring in the way expected
- 18. logic, proof, or support that you have for your claim
- 20. the methodological point of departure of scholarly research in both the natural and social sciences
- 22. able to be noticed or perceived; discernible
- 24. one which the researcher holds constant (controls) during an experiment
- 26. the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch
- 29. the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material
- 30. a representation of a person or thing or of a proposed structure, typically on a smaller scale than the original
