You are presented with the question "To identify that liquid 's boiling point requries" and the following answer choices: 
- vibrations of the atoms
 - kinetic energy
 - degrees Celsius
 - The bending of a ray of light
 - degrees celcius
 - Evaporation of water
 - evaporative cooling
 - fissures of hot, acidic water

Now knowing that heating a liquid can be used to identify that liquid 's boiling point and heat is caused by vibrations of the atoms and molecules of substances, choose the best answer.


 

 vibrations of the atoms
