Question

 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.

Answer 1

The answer is C. Liquid to gas.

Answer 2

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.
