The three processes by which thermal energy is transferred are conduction, convection, and radiation.
Which process can transfer thermal energy across empty space where no particles are present?
Which process involves the movement of warmer and cooler regions within a fluid?
Which two processes require a physical medium (matter) to transfer thermal energy?
301 exam-style questions on CIE IGCSE Physics 2.3 Transfer of thermal energy, covering 2.3.1a Thermal conductors and thermal insulators, 2.3.1b Explaining thermal conduction, 2.3.2 Convection, 2.3.3a Thermal radiation, 2.3.3b Surface colour and texture, 2.3.3c Rate of emission and absorption of radiation, and 2.3.4 Consequences of thermal energy transfer. Each one has a worked solution and a mark scheme showing where the marks go.
