You are presented with the question "conduction is increased with what?" and the following answer choices: 
- Time and energy
 - compaction
 - blood
 - evaporation
 - voltage
 - heat energy
 - motion
 - sweating

Now knowing that when a cooler object touches a warmer object , thermal conduction occurs and thermal conductivity also increases with compaction, choose the best answer.
