Statement (c): Entrophy can be created but not destrpoyed . Statment (d) : DeltaS_(system) is always zero for reversible processe in an isolated system
Which correctly represents the entropy (s) of an isolated system during a process.
Which one of the following statement is correct ? The system of linear equations, 2x + 3y = 4 and 4x + 6y = 7 , has
which of the following statement(s) is//are incorrect? Statement (a) : Reversible isothermal compression of an ideal gas represents the limiting minimum value of the work done (|omega|) by the surrounding on the system . Statement (b) : For thermodynamic changes in adiabatic process T^(((C_(p.m))/(R))) .P = constant Statement (c): DeltaS_(system) is zero for reversible adiabatic expansion of an ideal gas.
Read the following statements and select the correct option Statement 1: Euglena can be considered as a plant due to the presence of chlorophyll. Statement 2: Euglena cannot be classified on the basis of two kingdom system of classification.
Assertion :- The entropy of isolated system increases for spontancous process. Reason :- For spontancous process, DeltaS=+ve
Entropy ( S ) is a thermodynamic variable like pressure P , volume V and temperature T . Entropy of a thermodynamic system is a measure of disorder of molecular motion. Greater is disorder , greater is entropy. Change in entropy of a thermodynamic system is the ratio of heat supplied to absolute temperature.In an adiabatic reversible process, entropy remains constant while in any irreversible process entropy increases. In nature the processes are irreversible , therefore entropy of universe is continuoulsy increasing. After a long-long time, the energy available for work done will be :
