What’s on the States & Changes poster
A 6-row table: Change · From → to · Energy.
The six transitions.
- Melting — Solid → liquid — Absorbed
- Freezing — Liquid → solid — Released
- Vaporisation — Liquid → gas — Absorbed
- Condensation — Gas → liquid — Released
- Sublimation — Solid → gas — Absorbed
- Deposition — Gas → solid — Released
The plateau on a heating curve is latent heat: energy is overcoming intermolecular forces, not increasing kinetic energy.
Questions about the States & Changes poster
- What’s on the States & Changes poster?
- A 6-row table: Change · From → to · Energy. The six transitions. Melting — Solid → liquid — Absorbed; Freezing — Liquid → solid — Released; Vaporisation — Liquid → gas — Absorbed; Condensation — Gas → liquid — Released; Sublimation — Solid → gas — Absorbed; Deposition — Gas → solid — Released. The plateau on a heating curve is latent heat: energy is overcoming intermolecular forces, not increasing kinetic energy.
- Who is the States & Changes poster for?
- States & Changes belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning general chemistry can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the States & Changes poster?
- During a phase change, energy breaks bonds rather than raising temperature. A wall chart earns its place by being glanceable from where the work is happening, so States & Changes belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with States & Changes?
- Acids & Bases, Atomic Structure and Balancing Equations sit alongside States & Changes in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Acids & BasesAtomic StructureBalancing Equations
- Is the States & Changes poster free to download and print?
- Yes. States & Changes 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 States & Changes poster print at?
- States & Changes 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 States & Changes loses nothing.Printing guide
