endothermic- Endothermic describes a process that absorbs heat.Endothermic reactionsfeel cold. endpoint- The endpoint is when titration is stopped, typically because an indicator has changed color. The endpoint need not be the same as the equivalence point of a titration. energy level- An energy le...
