Across
- 2. corresponding in size or amount to something else
- 3. a fundamental principle of physics
- 4. able to be noticed or perceived; discernible
- 6. continuous physical force exerted on or against an object by something in contact with it
- 7. an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude
- 8. a temperature scale based on 0 o for the freezing point of water and 100 o for the boiling point of water
- 9. the fact of occurring in the way expected
- 14. a coherent, typically large body of matter with no definite shape.
- 15. 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
- 17. statements that link evidence back to reasons or claims
- 18. 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
- 20. the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great
- 21. an educated guess
- 23. the spreading of something more widely
- 26. if one variable increases the other will decrease, and if one variable decreases the other will increase
- 27. the quality or state of being natural
- 29. a representation of a person or thing or of a proposed structure, typically on a smaller scale than the original
- 30. the degree of compactness of a substance
- 31. 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.
Down
- 1. the state of not being definite or certain because you may want to change it later
- 5. the methodological point of departure of scholarly research in both the natural and social sciences
- 10. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization
- 11. the pressure exerted by the weight of the atmosphere
- 12. 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
- 13. energy energy associated with microscopic forms of energy
- 16. logic, proof, or support that you have for your claim
- 19. a statement in which a writer presents an assertion as truthful to substantiate an argument
- 22. one which the researcher holds constant (controls) during an experiment
- 24. the way in which a substance, typically a liquid, holds together; thickness or viscosity
- 25. a substance which does not readily allow the passage of heat or sound
- 28. the quality of being hot; high temperature
