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.
In baseball, a slider is a pitch halfway between a curveball and a fastball. When pitched, the slider breaks laterally and down, with more speed than a curve ball but less speed than a fastball. The break on the pitch is shorter than that of a curveball. The release technique of a slider is between a curve ball and a fastball. The slider is similar to the cutter.
