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.
Understand the basic concepts of the game. Baseball is a team sport played on a special field over the course of several periods of play, called innings. Each inning is further divided into two parts, the âtopâ and the âbottom,â during which one team tries to score points while the other team defends the field. A baseball that's hit and lands to the left of third base or the right of first base (as seen from home plate) is considered a âfoul ball,â which invalidates the play. 2  Foul lines are usually painted on the field to show where the border is. 3  There are regulation distances that define a proper baseball infield.
