Which statement(s) is correct,

`((delta H)/(delta T))_(P) - ((deltaU)/(deltaT))_(V) = R`

`((deltaH)/(deltaT))_(P) gt ((deltaU)/(deltaT))_(V)`

`((deltaH)/(deltaV))_(T)` for ideal gas is zero

All of these

False statement regarding second law of thermodynamics is

It is impossible to construct a machine working in cycles which transforms heat from a lower temperature region to higher temperature region without intervention of any external agency.

Heat cannot flow from a colder body to a hotter body on its own

For any spontaneous process taking place in an isolated system `DeltaS lt O`

All spontaneous processes are thermodynamically irreversible & entropy of the system increases in all spontaneous processes.

Which of the following statements is correct for any thermodynamics system

The internal energy change in all process

Internal energy and entropy are state function

The change in entropy can never be zero

The work done on an adiabatic process is always zero
