## 029. Thermodynamics (Thermodynamics processes)

• Thermodynamics processes
• Adiabatic process (No heat transfer)
• Isobaric process (Constant pressure)
• Isothermal process (Constant temperature)
• When they are starting from the same state, the work done by an isothermal process is always bigger than the work done by an adiabatic process.

$W_\text{isothermal} > W_\text{adiabatic}$
