The state of plasma is reached when matter acquires a temperature so high that some of the molecules and atoms are broken down into ions and electrons. Stellar and interstellar matter mostly occur as forms of plasma. On Earth, plasma exists in the ionosphere, in flames, and in chemical and nuclear explosions. Matter in a controlled thermonuclear reactor also exists in a plasma state. Plasma is most like a gas. However, it differs from un-ionized gas in that it is a good conductor of electricity and heat. Scientists hope to understand the occurrence of plasma in nature and to harness it as an inexpensive energy source. 26. Based on the passage, how can the cost of developing thermonuclear power with plasma be defended? A. It is applicable to all technologies. B.
