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 FLY: An infield fly is a fair ball (not including a line drive or an attempted bunt), which can be caught by an infielder with ordinary effort when 1st and 2nd or 1st, 2nd and 3rd bases are occupied before two are out. Any fielder can catch an infield fly. NOTE: All divisions play with an infield fly rule. *NOTE: When it seems apparent that a batted ball will be an infield fly, the umpire(s) shall immediately declare, infield fly, the batter is out to aid the runners.
