What is the composition of a simple fat?

Simple fats, also known as Acylglycerides or neutral fats, are those that are composed of esterified Glycerol (ester formation) by one, two or three fatty acids, in which case we talk about: monoacylglyceride, diacylglyceride or triacylglyceride respectively. Example types of them are oils, lard and tallow.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
