To determine whether a chemical reaction is spontaneous we must calculate the change in total entropy of the chemical system and its surroundings. This can be done directly using Î´ S Â° sys and âÎ´HÂ°/ T or indirectly using the change in Gibbs free energy Î´ G Â°.
Infield shift. The infield shift is a generic term used in baseball to describe an extreme defensive realignment from the standard positions to blanket one side of the field or another. Used almost exclusively against left-handed batters, it is designed to protect against extra base hits pulled hard into the gaps between the fielders on the right side.
Infield Gloves: Infield gloves are smaller gloves (generally 10 1/2  - 12) so that the fielder can easily pull the ball out of the glove and throw it. Too large of a glove would result in increased time needed to retrieve the ball and throw it to base-very important when a game can be decided by a tenth of a second.
