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.
The Crow Hop. For a throw in the infield, a player may need nothing more than her regular throwing footwork make a good throw. If the throw is across the diamond, she may need to add in a shuffle step. In the outfield, though, the target is often more than 100 feet away, so a shuffle step just wonât cut it.
