Answer the following T or F with explaination

Stationary processes: are maintained by external forces keep intensive state variables constant at fixed locations do not exist The triple line is seen in a temperature-density diagram The triple line is seen in a pressure-density diagram The triple point is the triple line projected onto the pressure-temperature plane..The second law of thermodynamics: can not be proven by any other principle of physics makes a statement about the equilibrium state is a consequence of the first law of thermodynamics In engineering, entropy could be considered as a "work coordinate" a system must "operate" to transfer energy in form of heat Examples of infinitesimal reversible work or heat are: volume work: chemical potential times change in amount of matter heat transfer: entropy times change in temperature energy transfer: temperature time change in entropy surface work: surfer time change in surface tension Seven watt is an amount of work is an amount of work flow is an amount of power can quantify heat flow across a system boundaries can be a unit for a thermodynamic state variable
