GCSE / high school (CBSE): polystyrene cup with a lid in a beaker, thermometer through the lid, a weighed solid (zinc powder into copper(II) sulfate solution, or a salt into water), measuring cylinder and stopwatch. ## What the template shows - Measure the temperature change when a metal displaces another or a salt dissolves - Ideally to 0.1 °C. Read every 30 s for 3 min, add the solid, stir and keep reading; extrapolate the cooling line back to the time of mixing to get ΔT - Cuts heat loss - Polystyrene cup - e.g. 25 cm³ of 0.5 mol dm⁻³ CuSO₄(aq) from the measuring cylinder. q = m c ΔT (m = mass of solution, c = 4.18 J g⁻¹ K⁻¹); ΔH = −q ÷ moles of the reactant not in excess - Stops the cup tipping over - Weighed solid - Excess zinc powder: Zn + CuSO₄ → ZnSO₄ + Cu, the temperature rises. Dissolving NH₄NO₃ in water makes it fall - Reaction setup Drawn with 14 shapes – every one editable in MolDraw. ## Sources - [Atkins, de Paula & Keeler, Atkins' Physical Chemistry, 11th ed., OUP 2018](https://openlibrary.org/isbn/9780198769866) Textbook ## How to use this template 1. Press **Edit in MolDraw**. The template opens on the canvas of the free MolDraw editor. 2. Change anything: move structures, edit atoms and labels, recolour highlights or delete what you do not need. 3. Add your own structures, arrows and text next to it, or combine several templates on one page. 4. Export the drawing as PNG, SVG or PDF for slides, worksheets, theses and papers. ## Frequently asked questions ### Is the Temperature change of a reaction template free? You can preview the Temperature change of a reaction template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates. ### Can I edit the Temperature change of a reaction template? Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it. ### Is the chemistry checked? Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page. ### Can I edit the glassware? Yes. Every piece of glassware is a MolDraw apparatus object: move, resize, recolour the liquid or swap a piece and the joints stay connected. ## More reaction setups templates [**Heating under reflux**Free · Reaction setups](https://www.moldraw.com/templates/setup-reflux/)[**Simple distillation**Free · Reaction setups](https://www.moldraw.com/templates/setup-distillation/)[**Dean–Stark water removal**Free · Reaction setups](https://www.moldraw.com/templates/setup-dean-stark/)[**Soxhlet extraction**Premium · Reaction setups](https://www.moldraw.com/templates/setup-soxhlet/)[**Vacuum filtration**Premium · Reaction setups](https://www.moldraw.com/templates/setup-vacuum-filtration/)[**Liquid–liquid extraction**Premium · Reaction setups](https://www.moldraw.com/templates/setup-extraction/)[**Reaction under nitrogen**Premium · Reaction setups](https://www.moldraw.com/templates/setup-inert/)[**Acid–base titration**Premium · Reaction setups](https://www.moldraw.com/templates/setup-titration/) ## Related pages [**Chemistry Lab Report Template**Free printable worksheet](https://www.moldraw.com/educational-materials/lab-report-template/)[**Titration Calculations Worksheet**Free printable worksheet](https://www.moldraw.com/educational-materials/titration-worksheet/)[**TLC and Rf Values Worksheet**Free printable worksheet](https://www.moldraw.com/educational-materials/tlc-rf-worksheet/)[**All Reaction setups templates**102 templates](https://www.moldraw.com/templates/reaction-setups/)[**All chemistry templates**370 templates in 29 categories](https://www.moldraw.com/templates/) MolDraw Pro Download all 370 templates - Export the 291 premium templates as PNG, SVG or PDF - AI chemistry assistant - Structure scanning from images - Cloud save and teaching slides [See Pro plans](https://www.moldraw.com/pricing) Free templates stay free.
