Dr. Ray has developed a new way to remove oil from wetlands in the event of an oil spill. To test his new process, Dr. Ray builds a scale model of a wetland in his lab and pours a small amount of oil into it. He then observes the rate at which his process is able to remove the oil from the model.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
