... is the sum of random distribution of KE and PE of all the molecules in the system. The substance contains internal energy, not heat. The word “heat” is used only when referring to the thermal energy actually in transit from hot to cold. 11. A flask containing boiling water is removed from the burner ...

... Irreversible process is one in which thermal system’s changes cannot be retraced, such as gas expanding to fill a vacuum through an open stopcock. A thermodynamic system can transfer its internal energy by changing the temperature (or phase) of another system of it can use its internal energy to do ...

... The standard state of a gas is the pure gas behaving as an ideal gas at 1 atm pressure and the temperature of interest (usually 25ºC). The standard enthalpy of reaction ( H ) is the enthalpy change for a reaction in which the reactants in their standard states yield products in their standard sta ...
