Explanation: ent knowledge suggests that volcanic outgassing on Venus produces SO2 ... then SO2 should be more abundant than S2, OCS, or H2S. The very low H2O

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.
