You are presented with the question "what causes the temperature of an object to increase?" and the following answer choices: 
- decrease in motion
 - flow of electrons
 - chronic impact
 - Greenhouse gases
 - thermometer
 - lowering the heat
 - It gets heated up
 - kinetic energy

Now knowing that friction causes the temperature of an object to increase and friction is chronic impact, impact is acute friction, choose the best answer.


 

   chronic impact
