SAT Subject Test Chemistry,10 edition

In question 8, a state function is one whose value depends only on the initial and final states of the
system; it is independent of the path taken in going from the initial to the final states. Examples of
state functions are pressure, volume, temperature, density, viscosity, enthalpy, internal energy,
entropy, and free energy. Two important functions that are not state functions are work and q, the
amount of heat transferred. So choice C is correct.

Type 2 Questions

These typically have three to five Roman numeral statements following each question. One or more
of these statements may be the correct answer. Following each statement, there are five lettered
choices with various combinations of the Roman numerals. You must select the combination that
includes all of the correct answers and excludes all of the incorrect answers.

Question    9

Substitute  the values  and convert temperatures    to  Kelvin  from    the problem and you have

So  choice  A   is  correct.

9. Which    of  the following   phenomena   are considered  to  illustrate  colligative properties?

I. The  lowering    of  the vapor   pressure    of  a   solvent by  a   solute

II. The raising of  the boiling point   of  a   solvent by  a   solute

III. The    lowering    of  the freezing    point   of  a   solvent by  a   solute

IV. Osmotic pressure
