Multiple Choice

Which statement A-D about the first law of thermodynamics ( $\Delta$ E_system = q + w) is not correct?

• A) q is the energy added to or removed from the system by a temperature difference.
• B) w is the energy added to or removed from the system by a deformation; that is, a force moves something.
• C) If the only work that is done is P-V work, then q = the change in enthalpy.
• D) (\(\Delta\)E_system is the change in the Gibbs free energy of the system.)
• E) The statements A-D are all correct.
