What’s on the Enthalpy poster
A 6-row table: Term · Is.
Standard enthalpy change definitions.
- ΔH formation — 1 mol of compound from its elements
- ΔH combustion — 1 mol burnt completely in oxygen
- ΔH neutralisation — 1 mol of water from acid and base
- ΔH atomisation — 1 mol of gaseous atoms
- Bond enthalpy — Breaking 1 mol of bonds, gaseous
- Lattice enthalpy — 1 mol of ionic solid from gaseous ions
Breaking bonds is endothermic; making them is exothermic. ΔH = bonds broken − bonds made.

- Who is the Enthalpy poster for?
- Enthalpy belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning physical chemistry can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Enthalpy poster?
- Negative ΔH means energy released. The sign is from the system's point of view. A wall chart earns its place by being glanceable from where the work is happening, so Enthalpy belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Enthalpy?
- Born-Haber Cycles, Equilibrium and Electrode Potentials sit alongside Enthalpy in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Born-Haber CyclesEquilibriumElectrode Potentials
- Is the Enthalpy poster free to download and print?
- Yes. Enthalpy downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Enthalpy poster print at?
- Enthalpy is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Enthalpy loses nothing.Printing guide
