Key Topics to Revise

1

Basic Terms and Definitions in Thermodynamics

  • System: Part of universe under thermodynamic investigation (e.g., gas in a cylinder)
  • Surroundings: Everything outside the system in the universe
  • Open System: Exchanges both matter and energy (hot coffee in open cup)
2

Types of Thermodynamic Processes

  • Isothermal Process: Temperature constant (ΔT = 0, ΔU = 0 for ideal gas)
  • Isobaric Process: Pressure constant (ΔP = 0, occurs at atmospheric pressure)
  • Isochoric Process: Volume constant (ΔV = 0, reactions in closed containers)
3

Work and Heat in Thermodynamics

  • Work (W): Energy transfer due to organized motion, measured in Joules
  • Heat (Q): Energy transfer due to temperature difference, measured in Joules
  • Sign Convention: +W (work done on system), -W (work done by system)
4

Internal Energy and First Law of Thermodynamics

  • Internal Energy (U): Total energy stored in a system, state function
  • First Law: Energy cannot be created or destroyed, only converted
  • Mathematical form: ΔU = Q + W
