You are presented with the question "When thermal conduction occurs, what always flows to what?" and the following answer choices: 
- ice to burning objects
 - heat energy
 - heat to cooler objects
 - converting electricity to heat
 - heat to metal objects
 - kinetic energy
 - cold to hot objects
 - Evaporation

Now knowing that when a cooler object touches a warmer object , thermal conduction occurs and heat always flow from warmer to cooler objects , choose the best answer.


 

   heat to cooler objects
