What’s on the Gas Volumes poster
A 4-row table: Condition · Definition · Molar volume.
Standard conditions and molar volumes.
- RTP — 25°C, 100 kPa — 24.0 dm³
- STP (modern) — 0°C, 100 kPa — 22.7 dm³
- STP (older) — 0°C, 1 atm — 22.4 dm³
- Any conditions — PV = nRT — Calculate
Avogadro's law: equal volumes of gases at the same temperature and pressure contain equal numbers of molecules — whatever the gas.
Questions about the Gas Volumes poster
- What’s on the Gas Volumes poster?
- A 4-row table: Condition · Definition · Molar volume. Standard conditions and molar volumes. RTP — 25°C, 100 kPa — 24.0 dm³; STP (modern) — 0°C, 100 kPa — 22.7 dm³; STP (older) — 0°C, 1 atm — 22.4 dm³; Any conditions — PV = nRT — Calculate. Avogadro's law: equal volumes of gases at the same temperature and pressure contain equal numbers of molecules — whatever the gas.
- Who is the Gas Volumes poster for?
- Gas Volumes belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning calculations can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Gas Volumes poster?
- 24 dm³ per mole at RTP. Use the ideal gas equation for anything else. A wall chart earns its place by being glanceable from where the work is happening, so Gas Volumes belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Gas Volumes?
- Atom Economy, Formula Summary and Concentration sit alongside Gas Volumes in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Atom EconomyFormula SummaryConcentration
- Is the Gas Volumes poster free to download and print?
- Yes. Gas Volumes 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 Gas Volumes poster print at?
- Gas Volumes 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 Gas Volumes loses nothing.Printing guide
