Answer all the questions please

Check out the change in entropy round your answer to two significant digits and be sure it has a crack in it simple final answer should be around to the power of -24.  Or around there.  Please check work

I Review Constants | Periodic Table O As the temperature of a perfect crystal increases, the random vibrations of the molecules decrease. Entropy, denoted by the symbol S, is the thermodynamic property describing the amount of molecular randomness or disorder in a system. It is a state thermodynamic function, meaning that its value does not depend on the path used to arrive at a specific set of conditions. Each system with a specified temperature, pressure, and composition has a unique entropy value. O At the melting point, the entropy of a system increases abruptly as the compound transforms into a liquid. The entropy change, A:S, is the difference in entropy between two states of a system, such as between the reactants and products of a reaction or between a flask before and after adding a mixture of gas. Prevlous Answera v Correct The third law of thermodynamics deals with the entropy of a system and the chemical bonding in the molecules. Whenever there is a change in phase from a…

When most elastomeric polymers (e.g., a rubber band)are stretched, the molecules become more ordered, asillustrated here: Suppose you stretch a rubber band. (a) Do you expect theentropy of the system to increase or decrease? (b) If therubber band were stretched isothermally, would heat needto be absorbed or emitted to maintain constant temperature?(c) Try this experiment: Stretch a rubber band andwait a moment. Then place the stretched rubber band onyour upper lip, and let it return suddenly to its unstretchedstate (remember to keep holding on!). What do you observe?Are your observations consistent with your answerto part (b)?
