| 1 | The system works on the principle that heat rises. | |
| 2 | Because the core is spinning more rapidly, it is increasing in heat and size. | |
| 3 | Short-term liquidity dried up under the heat of the financial and information drought. | |
| 4 | This thermal energy is contained in the rock and fluids beneath Earth's crust. | |
| 5 | So what they do is, they're describing how these thermodynamic properties change, in terms of only state functions and state variables. |
