when the molecules in a body move with increased speed, it's possible that the body will change from a    a.  liquid to a solid.      b.  gas to a liquid.    c.  liquid to a gas.      d.  gas to a solid.

 When the molecules in a body move with increased speed, it's possible that the body will change from a  C. liquid to a gas.
Given that increased speed means increased kinetic energy, the only possible solution is C because it is the only one which shows increased kinetic energy. The other options would be decreased, which means they are incorrect.
