WebApr 12, 2024 · An expression for the partial derivative (∂H / ∂p)T is given in Table 7.1, and the partial derivative (∂H / ∂T)p is the heat capacity at constant pressure (Eq. 5.6.3). These substitutions give us the desired relation μJT = (αT − 1)V Cp = (αT − 1)Vm Cp, m. This page titled 7.5: Partial Derivatives with Respect to T, p, and V is ... WebThe First Law of Thermodynamics. The change in a system’s energy during a thermodynamic process equals the heat added to the system, minus the work it performs on its environment. In differential form, this is written. (1) d E = d Q − d W. where Q represents heat and W represents work.
WebHeat Pump. A heat pump is basically a heat engine run in the reverse direction. In other words, a heat pump is a device that is used to transfer heat energy to a thermal reservoir. They are often used to transfer thermal energy by absorbing heat from a cold space and releasing it to a warmer one. Heat pumps transfer heat from a cold body to a ...
