Applicable to questions about heat, energy, work, and their interconversion in chemistry. See the tag wiki for a detailed list of topics. Questions tagged may also be tagged with [enthalpy], [energy], [free-energy] where appropriate.

Don't blame yourself. This is a badly-worded question. Products and reactants don't have "heat content", they have thermal energy. I.e., heat is not a property of substances—they don't 'contain heat …
There are actually two school of thought on this. One is that residual entropy (the entropy a substance has as a result of not being a perfectly ordered crystal at $\pu{0 K}$) is a thermodynamic en …
Using Mathematica, I obtained $T=546 K$, as follows. One of the nice things about using Mathematica for physical calculations is that it has the ability to understand/keep track of/cancel out/convert …
I'm looking at a textbook question (Engel & Reid, Thermodynamics, Statistical Thermodynamics & Kinetics, 4 ed, Q3.1) which states the following: The heat capacity $C_{\mathrm m,p}$ is less than …
The purpose of the original Joule (as opposed to JT) expansion experiment was to assess intermolecular interactions in real gases. In that experiment, Joule immersed twin glass globes into a water ba …
Suppose we carry out a reaction in a bomb calorimeter whose starting temperature is $298.15\ \mathrm K$. Here we assume $\Delta V$ is close enough to zero that we consider the process to be at constan …
I did find this paper from 2005 in which Zielkiewicz estimates the molar entropy of water at $\pu{298 K}$ [1]. It's behind a paywall, but the subsequent correction from 2006 is not [2]. This gives a …
I thought it would be fun to get an idea of how enormously large $W$ in $S = k\ln W$ is. I'd specifically like to estimate this for a mole of water at $\pu{1 atm}$ and $\pu{298 K}$. To do this, I nee …
