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?
- Thermal energy is transferred from the ball to the water until they are both at 75ºF.
- Thermal energy is transferred from the water to the ball until they are both at 75ºF.
- Thermal energy is transferred from the water to the ball until the ball is at 80ºF and the water is at 50ºF.
- 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.
