A 0.001 6-nm photon scatters from a free electron. For what (photon) scattering angle will the recoiling electron and scattered photon have the same kinetic energy?
Chapter 18: Law of Thermodynamics Zeroth Law of thermodynamics: If object A is in thermal equilibrium with object B, and object B is separately in thermal equilibrium with object C, then objects A and C will be in thermal equilibrium if they are placed in thermal contact The first law of thermodynamics is a statement of the conservation of energy. o If a system’s volume is constant, and heat is added, its internal energy increases. o If a system does work on the external world, and no heat is added, its internal energy decreases Work done by an expanding gas, constant pressure: W = PV o If the volume stays constant, nothing moves and no work is done. o If the temperature is constant, the pressure varies inversely with the v
