The following Chapter 2 Vocabulary terms may be found at the end of Chapter 2:
Summary of Terms page 49.
1. __________________is the lowest possible
temperature, which is the temperature at which the atoms of a substance have no
kinetic energy,
2. __________________was a medieval endeavor
concerned with turning other metals into gold
3. __________________ extremely small fundamental
units of Matter
4. __________________is a gas law that describes the
direct relationship between the volumes of a gas and the number of gas
particles it contains at constant temperature and pressure
5. __________________ is evaporation in which
bubbles form beneath the surface of a liquid. (When the vapor pressure of the
liquid equal the external pressure applied to the
liquid)
6. __________________is a gas law that describes the
indirect relationship between the pressure of a gas sample and its volume at
constant temperature(The volume of a gas varies
inversely proportional to a change in its pressure at constant temperature)
7. __________________Is a gas law that describes the
direct relationship between the volume of a gas sample and its absolute (or
Kelvin) temperature at constant pressure. (The Volume of a Gas varies Directly
proportional to its Kelvin temperature at constant pressure).
8. __________________ is the transformation of a gas
to a liquid.
9. __________________ is the amount of mass
contained in a sample divided by the volume of the sample.
10. __________________ is the capacity to do work
11. __________________
is the
transformation of a liquid to a gas.
12. __________________ is the transformation of a
liquid to a solid
13. __________________is matter that has neither a
definite volume nor a definite shape, always filling any space available to it.
14. __________________
is the energy that flows
from one object to another because of a temperature difference between the two
15. __________________ is defined as the absence of
heat,
16. __________________is a gas law that summarizes
the pressure, volume, Kelvin temperature, and number of particles of a gas.
Summarized by the formula PV=nRT (Where T must be
Kelvin temperature)
17__________________is energy due to motion.
18. __________________is
a theory that defines the properties of solids, liquids, and gases by proposing
that they consist of rapidly moving tiny particles, either atoms or molecules,
or both.
19. __________________
is matter that has
definite volume but no definite shape, assuming the shape of its container
20. __________________ is the quantitative measure of
how much matter an object contains
21. __________________ is the transformation of a
solid to a liquid
22. __________________ is an extremely small fundamental
structure built of atoms
23. __________________is stored energy or energy of
position
24. __________________is matter that has definite
shape and definite volume.
25. __________________
is how warm or cold an
object relative to some standard. Also, a measure of the average kinetic energy
per molecule of a substance, measured in degrees Celsius, degrees Fahrenheit,
or kelvin.
26. __________________
is an instrument used to
measure temperature
27. __________________is the amount of space an
object occupies
28. __________________ is the gravitational force of
attraction between two bodies (where one is usually the Earth)
29. __________________ is the transformation of a
solid directly to a gas
30. __________________ is the transformation of a gas
directly to a solid
31. __________________is the temperature and pressure
at which all three phases of matter (solid, liquid, and gas) are in equilibrium
32. __________________
is an instrument used to
measure atmospheric pressure
