You are presented with the question "what happens when a cooler object touches a warmer object?" and the following answer choices: 
- Temperature changing
 - they die
 - thermometer
 - flow of electrons
 - heat removed from the center
 - matter vibrating
 - h2o loss
 - converting electricity to heat

Now knowing that when a cooler object touches a warmer object , thermal conduction occurs and thermal conduction removes heat from the center, choose the best answer.
