Thermal physics — IGCSE Sciences - Co-Ordinated (0973) questions by topic
Thermal physics questions ask which mechanism carries solar energy across empty space to reach the Earth, why a vacuum flask's shiny surfaces keep a drink hot, why a jar's metal lid sticks after refrigeration, and how convection moves air around a heater, from 1 to 11 marks.
Identify, state and describe top the command words in this IGCSE Co-ordinated Sciences set, with complete and explain also frequent: describe the mechanism of heat loss, not just name it. 20 real questions from 2023 to 2025 papers sit below. Submitting each answer for instant marking shows immediately whether conduction, convection or radiation was the term the mark scheme wanted.
