Solids, Liquids and Gases
Bank: Endothermic, Idea Gas, Pressure, Melting point, vapor
pressure, Gay-Lussac's law, barometer, exothermic, van der waals,
vaporization. dipole-dipole, hydrogen bonding, Charles
law viscosity, condensation, amorphous solid, boiling
point.
1. A _____________________ shows an atmospheric reading of
4 ATM, which is a reading of _____________________.
2. For water at standard pressure, 100°C is the
__________________________.
3. Water (H2O) has a higher than expected boiling point
because of the intermolecular force called _______________________
between the molecules of water.
4. Honey has a high resistance to flow as it moves through
a tube, as opposed to water, which has a low resistance to flow.
Honey, therefore has a much higher _______________________.
5. The temperature at which a substance turns from solid to
liquid is known as its _______________________.
6. Table salt is a _________________________, while
glass is an _________________________.
7. Methane gas is held in a tank at constant volume, and
experiences increased pressure because of an increase in
temperature. This is an example of __________________________.
8. The __________________________ equation applies all the
forces involved in the kinetic energy of a gas, such as particle
size of molecules, while the __________________________ law
neglects these forces, and is thus NOT accurate at low
temperatures, extremely low volumes, or extremely high
pressures.
9. An __________________________ reaction releases
energy, whereas an __________________________ reaction absorbs
energy.
10. The strength of _______________________ forces is
stronger than London dispersion forces and is synonymous for the
force of attraction between two polar molecules.
11. As water is heated from 25°C to 100°C, the atmospheric
reading above the water changes from 760 torr (1 ATM) to 780 torr.
This slight increase in pressure is mainly attributed to
_____________________________ caused by increased temperature.
12. _________________________ states that as temperature
increases, volume also increases.
13. To reheat liquid natural gas from its liquid form to a
gaseous state, it is run through a process that is called
_____________________________.
14. When a gas turns to a liquid during cooling, it has
gone through the phase transition known as
_________________________.

It is possible that in one species, you might find two protein
sequences as two domains in one polypeptide, but in another species
the two sequences may exist as separate subunits that associate
together to make a protein.
A) False; this never happens.
B) True; there are many examples of this.
