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.
Play 1: Bases loaded, one out. The batter pops up a ball in the infield, which is called an infield fly by the umpire. The runner from first (R1) strays off the bag. The first baseman catches the ball, and then steps on the bag before R1 gets back to the bag.
