Weather and Climate I: Basic Elements
The pattern of the rise and fall of air temperature over a day and over a year at any given place on the surface…
Item NG047004: When a ball that is 80ºF is placed in a bucket of water that is 50ºF, thermal energy is transferred from the ball to the water until they are both at the same temperature.
The temperature of a clay ball is 80ºF and the temperature of the water in a bucket is 50ºF. 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 55ºF.
- Thermal energy is transferred from the water to the ball until they are both at 55ºF.
- Thermal energy is transferred from the water to the ball until the ball is at 50ºF and the water is at 80ºF.
- No thermal energy would be transferred between the ball and the water, so the ball will stay at 80ºF and the water will stay at 50ºF.
