Affecting Entropy
If you increase temperature, you increaseentropy. (1) More energy put into a system excitesthe molecules and the amount of random activity. (2) As a gasexpands in a system, entropy increases. (3) When a solidbecomes a liquid, its entropy increases.
Correspondingly, does higher entropy mean more energy?
Entropy is a measure of randomness or disorder ina system. Gases have higher entropy than liquids, andliquids have higher entropy than solids. Scientists refer tothe measure of randomness or disorder within a system asentropy. High entropy means high disorder and lowenergy (Figure 1).
Similarly, what is entropy of a system?
Entropy, the measure of a system's thermalenergy per unit temperature that is unavailable for doing usefulwork. Because work is obtained from ordered molecular motion, theamount of entropy is also a measure of the moleculardisorder, or randomness, of a system.
Keep in mind that entropy increases withtemperature. However, at higher temperatures, a certainamount of heat added to the system causes a smaller change inentropy than the same amount of heat at a lowertemperature. The formula is ΔS=QT. The change inentropy is related to heat.
