Talitha is performing an experiment on how plants get water up to their leaves. She adds two drops of blue food coloring to a beaker of water. Then, she hears a fire alarm and heads outside. When Talitha gets back to the classroom, the water in the beaker is all pale blue. She recognizes that the process of has caused the dye to spread evenly through the water.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

It was crowded with sewer like smells. bad sewer systems
