In computing, del (or erase) is a command in command-line interpreters such as COMMAND.COM, cmd.exe, 4DOS, NDOS, 4OS2, 4NT and Windows PowerShell. It is used to delete one or more files or directories from a file system .
Here, U is internal energy, T is absolute temperature, S is entropy, P is pressure, and V is volume. This is only one expression of the fundamental thermodynamic relation. It may be expressed in other ways, using different variables (e.g. using thermodynamic potentials). For example, the fundamental relation may be expressed in terms of the ...
This is possible provided the total entropy change of the system plus the surroundings is positive as required by the second law: ΔS tot = ΔS + ΔS R > 0. For the three examples given above: 1) Heat can be transferred from a region of lower temperature to a higher temperature in a refrigerator or in a heat pump. These machines must provide ...
From this plot, − Δ r H / R is the slope, and Δ r S / R is the intercept of the linear fit. By measuring the equilibrium constant, K eq, at different temperatures, the Van 't Hoff plot can be used to assess a reaction when temperature changes.

In MS-DOS and Microsoft Windows, the temporary directory is set by the environment variable TEMP or TMP. [1] Using the Window API, one can find the path to the temporary directory using the GetTempPath2 function, [2] or one can obtain a path to a uniquely-named temporary file using the GetTempFileName function.
