The topic contains 4 subtopics, 13 topic questions and 17 marks in total. Rows count only the parts tagged to that subtopic, keep the same colour in both charts and repeat paper count, tagged marks and year range in the native table. ## Topic question count and mark distribution Subtopics are on the vertical axis and sorted from highest to lowest. Only the parts whose knowledge graph matches a subtopic are counted for it, and percentages are each row's share of the tagged total in that chart. A part tagged to several subtopics is counted in each bar, so the bars are not a partition of the topic total. ### Questions by subtopic question items - [1 understand that a physical property that varies with temperature may be used for the measurement of temperature and state examples of such properties, including the density of a liquid, volume of a gas at constant pressure, resistance of a metal, e.m.f. of a thermocouple](https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/1-understand-that-a-physical-property-that-varies-with-temperature-may-be-used-for/) (4 papers) — 6 · 40.0% - [2 understand that the scale of thermodynamic temperature does not depend on the property of any particular substance](https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/2-understand-that-the-scale-of-thermodynamic-temperature-does-not-depend-on-the/) (3 papers) — 3 · 20.0% - [3 convert temperatures between kelvin and degrees Celsius and recall that $T / K = \theta / °C + 273.15$](https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/3-convert-temperatures-between-kelvin-and-degrees-celsius-and-recall-that-t-k-theta-c/) (3 papers) — 3 · 20.0% - [4 understand that the lowest possible temperature is zero kelvin on the thermodynamic temperature scale and that this is known as absolute zero](https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/4-understand-that-the-lowest-possible-temperature-is-zero-kelvin-on-the-thermodynamic/) (2 papers) — 3 · 20.0% ### Marks by subtopic marks - [1 understand that a physical property that varies with temperature may be used for the measurement of temperature and state examples of such properties, including the density of a liquid, volume of a gas at constant pressure, resistance of a metal, e.m.f. of a thermocouple](https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/1-understand-that-a-physical-property-that-varies-with-temperature-may-be-used-for/) (4 papers) — 8 · 42.1% - [3 convert temperatures between kelvin and degrees Celsius and recall that $T / K = \theta / °C + 273.15$](https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/3-convert-temperatures-between-kelvin-and-degrees-celsius-and-recall-that-t-k-theta-c/) (3 papers) — 5 · 26.3% - [2 understand that the scale of thermodynamic temperature does not depend on the property of any particular substance](https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/2-understand-that-the-scale-of-thermodynamic-temperature-does-not-depend-on-the/) (3 papers) — 3 · 15.8% - [4 understand that the lowest possible temperature is zero kelvin on the thermodynamic temperature scale and that this is known as absolute zero](https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/4-understand-that-the-lowest-possible-temperature-is-zero-kelvin-on-the-thermodynamic/) (2 papers) — 3 · 15.8% ## Subtopic comparison matrix Curriculum order is by syllabus number, then alphabetically.

They are ordered by syllabus number, then alphabetically, and each row opens a page of matching past-paper questions. **How are the subtopic question and mark totals calculated?** A multiple-choice question contributes one item and its marks to every subtopic it is tagged with. A structured question contributes one item per tagged part, and that part’s marks; untagged parts of the same question are not counted here. A part tagged to several subtopics therefore appears under each of them. **Why do some subtopics have no numbered prefix?** Practical-skills statements and some syllabus bullets are unnumbered. Numbered statements come first; unnumbered statements and ties are sorted alphabetically. **Is the LaTeX rendered without JavaScript?** Yes. Subtopics that contain formulas are converted to static KaTeX HTML during the build, and the KaTeX stylesheet is served from the same site. --- Full page with native tables, bar charts and Practice Hub links: https://www.examsci.com/topics/cie-ial/physics/9702-paper-4/temperature-scales/
