In a closed system the entropy is constant.

As a gas is heated, its entropy generally increases. This is because the increased molecular motion and disorder associated with higher temperatures lead to a greater number of microstates available to the system, resulting in higher entropy.
The entropy of the system increases during the sublimation of I2(s) to I2(g) because the randomness and disorder of the gas phase is higher compared to the solid phase. Therefore, the entropy of the reaction is positive.
Reactions that increase the moles of gas will increase in entropy.
The entropy increases, as going from a solid to a gas increases disorder or randomness in the system. This is because gases have more freedom of movement and energy compared to solids.
The entropy increases in this reaction, as the solid reactant (I2(s)) is becoming a gas (I2(g)), which represents a higher degree of disorder and randomness on a molecular level. The increased entropy contributes to the spontaneity of the reaction.
if there is an increase in the number of gas molecules , then ^S > 0
