Document Summary

Those that can proceed without any outside intervention. A measure of the randomness or disorder of a system. Reversible process: the system changes in such a way that the system and surroundings can be put back in their original states by exactly reversing the process. Thermodynamics tells us about the direction and the extent of a reaction. Temp is a measure of the ave. kinetic energy. A specific microscopic configuration of a thermodynamic system that the system may occupy with a certain probability in the course of its thermal fluctuations. The number of microstates and entropy tends to increase with increases in temperature volume, independently moving molecules. Kb = r/na = 1. 38 x 10-23 j/k. With the number of microstates in the system. With the number of particles present and with temperature. When a solid is dissolved in a solvent. When gases are formed from liquids and solids. When the number of gas molecules increases.
