Section 11.2 State Functions
and Path Functions (p. 513-515)
This tutorial defines and explores the difference between
state and path functions using a travel analogy that leads
into a discussion of energy, enthalpy, heat, and work.
Section 11.4 PV
Work (p. 518-523)
An animated tutorial of an internal combustion engine shows
how a system undergoing an exothermic reaction can do work
on its surroundings and allows you to explore the relationship
between pressure, volume and work. Includes practice problems.
Section 11.5 Internal
Energy (p. 523-524)
This tutorial explores how energy is exchanged between a system
and its surroundings as heat and/or work, and how this transfer
in turn affects the internal energy (E) of a system.
Includes practice problems.
Section 11.6 Heating Curves
(p. 524-531)
Use interactive heating curve diagrams to explore phase changes,
heat of fusion, and heat of vaporization. Macroscopic views
of ice melting and water boiling are shown in sync with the
appropriate sections of the heating curve. Includes practice
exercises.
Section 11.7 Estimating
Enthalpy Changes (p. 531-535)
Learn how to use average bond energies to estimate the energy
released during a combustion reaction. Includes practice problems.
Section 11.8 Calorimetry
(p. 535-537)
This tutorial demonstrates how a bomb calorimeter works, and
walks through the equations used to solve calorimetry problems.
Includes an interactive experiment.
Section 11.11 Hess's Law
(p. 542-545)
This tutorial explains Hess's law of constant heat of summation
using animated sample problems and step-by-step descriptions.
Includes practice exercises.
