The positive value of $\Delta S$ indicates that

Which of the following statements is incorrect?

Among the following processes,for which process is the change in entropy $(\Delta S)$ negative?

Heat has a randomizing influence on a system,and temperature is the measure of the average chaotic motion of particles in the system. Write the mathematical relation that relates these three parameters.

Which of the following processes is associated with a decrease in entropy?

The $S^o$ of the following substances are:
$CH_{4(g)} : 186.2 \ J \ K^{-1} \ mol^{-1}$
$O_{2(g)} : 205.2 \ J \ K^{-1} \ mol^{-1}$
$CO_{2(g)} : 213.6 \ J \ K^{-1} \ mol^{-1}$
$H_2O_{(l)} : 69.9 \ J \ K^{-1} \ mol^{-1}$
The entropy change $\Delta S^o$ . . . . . . $J \ K^{-1} \ mol^{-1}$ for the reaction
$CH_{4(g)} + 2O_{2(g)} \to CO_{2(g)} + 2H_2O_{(l)}$ is
