Work

• How Does Adiabatic vs. Isothermal Compression Affect Gas Work?
  For the same ideal gas and compression ratio, reversible adiabatic compression requires more work than isothermal compression because the gas heats up.
• Can Conservative Forces Change a System’s Mechanical Energy?
  A conservative force can change kinetic energy, but its work is offset by an equal change in potential energy when no nonconservative work acts.
