Scope and sources
Cambridge IGCSE Physics 0625 · 2026–2028 v2 · Original learning materials.
Experiments that show good and bad thermal conductors (2.3.1.1); Supplement: conduction in solids by lattice vibrations and, in metals, by free electrons (2.3.1.2), why most liquids and gases conduct badly (2.3.1.3), and solids that conduct less well than good conductors but better than insulators (2.3.1.4); convection in liquids and gases, explained by density changes, with an experiment to show it (2.3.2.1, 2.3.2.2); everyday applications and consequences of conduction, convection and radiation, including heating a pan and heating a room (2.3.4.1). Thermal radiation and the vacuum flask are in Thermal radiation; conductivity numbers and rates are not covered.
Apparatus, amounts and times in the experiment are illustrative. Real practical work follows a teacher-approved safety method.
