### The Specfic and Molar Gas Constant
The molar gas constant is represented by $\tilde R = 8.31 \text{JK}^{-1}\text{mol}^{-1}$.
The specific gas constant is $R = \frac{\tilde{R}}{M}$.
The SI unit for the specific gas constant is J kg$^{-1}$ mol$^{-1}$.
The SI unit for molar mass is kg mol$^{-1}$.
## Thermodynamic Processes and Cycles
When a thermodynamic system changes from one state to another it is said to execute a *process*.
