hi everybody i want to make report in cold plasma and what is the difference between cold plasma and the plasma in the sun .
Can you please elaborate about what is "cold plasma"? You should read the article at wikipedia.org about plasmas (cold plasma is mentioned in the article), and also do a search on cold plasma at wikipedia (that gives you an interesting hit with more information on a class of plasmas).
After you read the wikipedia articles, if you still have questions, please post them here.
The term "cold plasma" is typically applied to plasmas in which the ions are at room temperature. The electrons need to be fairly energetic (at least few eV) in order to sustain the plasma, but the ions don't have to be. This is how low temperature atmospheric plasma jets, currently being studied for use in medicine, work.
