Is the entropy of the universe constant ?

A : The energy of the universe is constant, whereas the entropy of the universe is continuously increasing. R : For spontaneous process Delta S gt 0 .

Which of the following statement is true regarding the entropy of the universe?

The universe is

As per second law of thermodynamics a process taken place spontaneously if and only if the entropy of the universe increases due to the process. Change in entropy is given by Delta S = (Q_(rev))/(T) What is the change in entropy of the universe due to the following reaction occuring at 27^(@)C ? A + 2B rarr C + 2D, Delta H = +1.8 kJ mol^(-1) Molar entropy values of A, B, C and D are 1,2,3 and 4 JK^(-1) mol^(-1) respectively.

As per second law of thermodynamics a process taken place spontaneously if and only if the entropy of the universe increases due to the process. Change in entropy is given by Delta S = (Q_(rev))/(T) A gas C_(V) = (0.2 T) Cal K^(-1) . What is the change in its entropy when one mole of it is heated from 27^(@)C to 127^(@)C at constant volume ?

Which of the following statement is true. The entropy if the universe

In the equation of state of an ideal gas PV =nRT , the value of the universal gas constant is not correct :

The specific heat capacity of hydrogen at constant'pressure and constant volume are 14280 J kg ^(-1) K ^(-1) and 10110 J kg ^(-1) K ^(-1) respectively. Calculate the value of the universal gas constant.

The value of entropy of the universe is always

The unit of universal gas constant is
