Study Notes
- Thermodynamics deals with energy, heat, and work, governed by fundamental laws.
1st Law of Thermodynamics
- The 1st Law is also known as the Conservation of Energy
- Change in internal energy ($\Delta U$) equals heat added to the system ($Q$) minus work done by the system ($W$): $\Delta U = Q - W$.
- Work ($W$) calculated as the integral of pressure ($P$) with respect to volume ($V$): $W = \int{PdV}$.
Special Cases of the 1st Law
- Isochoric processes occur at constant volume, resulting in $W = 0$ and $\Delta U = Q$.
- Isobaric processes occur at constant pressure, resulting in $W = P\Delta V$ and $\Delta U = Q - P\Delta V$.
- Isothermal processes occur at constant temperature, resulting in $\Delta U = 0$ and $Q = W$.
- Adiabatic processes have no heat exchange, resulting in $Q = 0$ and $\Delta U = -W$.
2nd Law of Thermodynamics
- Entropy ($S$) is defined as $S = k_B \ln{\Omega}$, where $k_B$ is the Boltzmann constant and $\Omega$ is the number of microstates.
- Change in entropy ($\Delta S$) is the heat added in a reversible process ($Q_{rev}$) divided by temperature ($T$): $\Delta S = \frac{Q_{rev}}{T}$.
- The 2nd Law states that the change in entropy of the universe is always greater than or equal to zero: $\Delta S_{universe} \ge 0$.
Heat Engines
- Efficiency ($e$) is the net work done ($W_{net}$) divided by heat from the hot reservoir ($Q_H$), which is $e = \frac{W_{net}}{Q_H} = 1 - \frac{Q_C}{Q_H}$.
- $Q_C$ represents heat dumped to the cold reservoir
- For an ideal Carnot engine, efficiency ($e_{carnot}$) is $1 - \frac{T_C}{T_H}$, where $T_C$ and $T_H$ are temperatures of cold and hot reservoirs, respectively.
Heat Pumps
- Coefficient of Performance ($COP$) is the heat delivered to the hot reservoir ($Q_H$) divided by the work required ($W_{in}$): $COP = \frac{Q_H}{W_{in}}$.
- For an ideal Carnot heat pump, $COP_{carnot}$ is $\frac{T_H}{T_H - T_C}$, where $T_H$ and $T_C$ are temperatures of hot and cold reservoirs.
