Classify each process by its individual effect on the entropy of the universe,
1 - a process run infinitesimally slowly at equilibrium and reversed to it's original state
2 - solid and liquid water combined together at stp
3 - motion of a frictionless pendulum
4 - titration of sodium hydroxide and hydrochloric acid
5 - ice melting to water above the melting point
6 - sublimation of naphthalene (mothballs)

•what conclusions can you make about the relationship between the volume of a gas and its temperature? • what conclusions can you make about the relationship between the volume of a gas and its pressure? • what possible variables have you not accounted for? as you did the procedures, is it possible that the atmospheric pressure may have changed? if it did change over the course of your experiment, then how would your results have been affected?
