Charged pril Which of the following correctly describes why the plum pudding model is no longer accepted as an accurate model of the atom?
There aren't actually negatively charged particles in atoms.
Scientists found new evidence and revised the theory to fit the data better.
Ο Ο Ο Ο
Scientists discovered that atoms actually have positively charged particles dispersed throughout a negative mass.
Scientists revised the evidence to fit this model of the atom better.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

i need an image of the diagram

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.
