A deep-space research probe, Aegis-7, is in a stable orbit around Venus, where it is exposed to continuous, high-intensity solar radiation.
Explain why the temperature of Aegis-7 does not continue to rise indefinitely, even though it is constantly absorbing thermal radiation from the Sun.
7 exam-style questions on Edexcel GCSE Physics 5.3 Black body radiation, covering 5.3.1 Emission of radiation and temperature, 5.3.2 Radiation balance and constant temperature, and 5.3.3 The temperature of the Earth. Each one has a worked solution and a mark scheme showing where the marks go.
