Key Topics to Revise
1
Basic Concepts and Laws
- Thermodynamics deals with macroscopic variables like pressure (P), volume (V), temperature (T), and internal energy (U)
- Thermal equilibrium occurs when there is no net heat flow between systems
- Zeroth Law: If two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other
2
Specific Heat Capacity and Molar Heat Capacity
- Specific heat capacity is heat required per unit mass per unit temperature change
- Molar heat capacity is heat required per mole per unit temperature change
- For gases, we have two types: Cp (constant pressure) and Cv (constant volume)
3
Thermodynamic Processes
- Isothermal process: Temperature constant (T = constant)
- Adiabatic process: No heat exchange (Q = 0)
- Isobaric process: Pressure constant (P = constant)
4
Heat Engines and Second Law
- Heat engine converts heat energy into mechanical work
- No engine can convert 100% heat into work (Kelvin-Planck statement)
- Heat cannot flow from cold to hot body without external work (Clausius statement)
