Estimated Time: 30 minutes

• Students are placed in small groups and asked to describe the interaction between two black body objects of different temperatures in a vacuum.
• The small groups must also determine how the interaction will change if one black body object is replaced with one that reflects one-third of the incident light.

• Familiarity with the first and second thermodynamic laws
• Basic understanding of electromagnetic radiation and its properties
• Basic understanding of black body thermodynamics is useful
