PHYS 1220 Exam 1 Study Guide

This exam asesses course standards 7–12.  If you can do the tasks described below, you will satisfy the standards on the exam.

Standard 7

Calculate the internal energy of a monatomic or diatomic ideal gas.

Calculate the heat transfer needed to change the temperature of a monatomic or diatomic ideal gas at constant volume.

Calculate the heat transfer needed to change the temperature of a monatomic or diatomic ideal gas at constant pressure.

Standard 8

Identify the phase or phases of a substance at any point depicted in a p, T phase diagram.

Identify how volume depends on the point in a p, T phase diagram, and how volume changes from one point to another.

Find the triple point and critical point in a p, T phase diagram of a pure substance.  Explain what occurs at those two points.

Standard 9

Relate heat input, work output, and internal energy change along a thermodynamic path.  Given two of those quantities, find the third.

Standard 10

Determine the heat input, work output, and internal energy change of isothermal, isobaric, isochoric, and adiabatic processes of monatomic or diatomic ideal gases.

Determine the work done in any constant-pressure process for which the volume change is known.

Standard 11

Explain why energy and matter tend to spread out to fill the space available.

Explain why systems spontaneously and irreversibly transform from “ordered” to “disordered” states.

Relate thermodynamic temperature to entropy change and energy gain.

Relate equilibrium to entropy.

Standard 12

Calculate the entropy change of an object gaining or losing heat at a constant temperature.

Calculate the entropy change of an ideal gas undergoing a free expansion.

Calculate the entropy change of an object changing temperature as a result of a heat transfer.

Calculate the entropy of a state from its multiplicity.
