In the picture, groups of pigments that capture light energy are located on the

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.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

the growth of the plants is affected by the heat of the light. what is the student doing?
