Item NG047003: When a ball that is 50ºF is placed in a bucket of water that is 80ºF, thermal energy is transferred from the water to the ball until they are both the same temperature.

The temperature of a clay ball is 50ºF and the temperature of the water in a bucket is 80ºF.  A student places the clay ball into the bucket of water.  Which of the following describes how thermal energy is transferred between the ball and the water?

  1. Thermal energy is transferred from the ball to the water until they are both at 75ºF.
  2. Thermal energy is transferred from the water to the ball until they are both at 75ºF.
  3. Thermal energy is transferred from the water to the ball until the ball is at 80ºF and the water is at 50ºF.
  4. No thermal energy would be transferred between the ball and the water, so the ball will stay at 50ºF and the water will stay at 80ºF.
