Bryce Harper, conservative hero. Bryce Harper is a conservative hero. The star rookie for the Washington Nationals has woken up Major League Baseball, and watching it unfold has reminded me of nothing so much as the collapse of the old political paradigms and the inevitable and upcoming rebirth of conservatism in November.
Q = mâ¢Câ¢Î´T. where Q is the quantity of heat transferred to or from the object, m is the mass of the object, C is the specific heat capacity of the material the object is composed of, and Î´T is the resulting temperature change of the object.
If you take the solid and liquid, or liquid and gas, or whatever the two phases are, then at the phase change the Gibbs free energies of the two components are the same because the two states are in equilibrium. The Gibbs free energy change in the transition is: $$ \Delta G = \Delta H - T \Delta S $$ where $\Delta H$ is the change in enthalpy and $\Delta S$ is the change in entropy. The temperature $T$ is a constant because the phase change occurs at constant temperature. At the phase change temperature $\Delta G$ is zero so: $$ \Delta H = T \Delta S $$ The enthalpy change $\Delta H$ is basically the heat emitted or absorbed during the phase change, and it's balanced by the change in entropy due to the phase change.
