Item NG024003: When a warm plastic block is in contact with a cold metal block, thermal energy will be transferred from the warm block to the cold block until they reach the same temperature.

The temperature of a plastic block is 60°F, and the temperature of a metal block is 40°F. A student puts the plastic block on top of the metal block. Will the blocks ever reach the same temperature? Why or why not?

  1. Yes, but only for a little while because the metal block will continue to get warmer and the plastic block will continue to cool
  2. Yes, because energy will be transferred from the plastic block to the metal block until they reach the same temperature
  3. No, because the temperature difference is not large enough for energy to be transferred
  4. No, because the blocks are made of different materials
