Answer the following question given this paragraph: Plasma is a state of matter that resembles a gas but has certain properties that gases do not have. Like a gas, plasma consists of particles of matter than can pull apart and spread out, so it lacks a fixed volume and a fixed shape. Unlike a gas, plasma can conduct electricity and respond to a magnetic field. That's because plasma consists of electrically charged particles called ions, instead of uncharged particles such as atoms or molecules. This gives plasma other interesting properties as well. For example, plasma glows with colored light when electricity passes through it. You can learn more about plasma at this URL: http://www. youtube. com/watch?v=VkeSI_B5Ljc. Q: What is the state of matter that resembles a gas, but is made of ions, giving it different properties than a typical gas? A:
OPTIONS:
- gamma
- vapor
- acid
- plasma
plasma

Answer the following question given this paragraph: Chadwick's work resulted in a new understanding of the nucleus of the atom; it is comprised of both protons and neutrons. Because the masses of subatomic particles are so small, a new unit, called an atomic mass unit (amu), was defined. Protons and neutrons each have a mass of approximately one amu. The Table below describes the characteristics of the three subatomic particles we have discussed. Q: Because the masses of subatomic particles are so small, a new unit, called what, was defined? A:
OPTIONS:
- atomic volume unit
- particle mass unit
- nuclear mass unit
- atomic mass unit

Answer: atomic mass unit
