Answer: Enantiomers are a sub class of stereo isomers,which are actually non super imposable images of each other. Explanation: the only difference in property between them is the effect of polarized light on them, the polarized light is rotated by both of them in equal magnitude, but in opposite direction.
Special Note:Because of varying water temperatures, and for the safety of participants, classes should vary depending on the water temperature. High aerobic activity in high temperature water can be dangerous. It's important to remember that you can never keep everybody happy regarding water temperature. If a pool is used for just one of the above-mentioned programs, you do not have a problem. The water temperature at the average multi-purpose pool in the USA is 84 to 86 degrees.
Another problem is heating. I'd like to keep the pool at 82, but according to all I've read I need to keep the room 2 degrees higher (to limit humidity). In this area that means I will use the heater most of the year and that is frightening, energy-use wise.
