Item NG056002: Energy is transferred when an ice cube is placed in a cup of hot tea, and energy is transferred when a spring is used to roll a ball across the floor.
Consider the following situations:
Situation 1: An ice cube is placed in a cup of hot tea.
Situation 2: A spring is used to roll a ball across the floor.
Is energy being transferred in either of these situations?
- Energy is transferred in both situations.
- Energy is NOT transferred in either situation.
- Energy is transferred when an ice cube is placed in a cup of hot tea, but energy is NOT transferred when a spring is used to roll a ball across the floor.
- Energy is transferred when a spring is used to roll a ball across the floor, but energy is NOT transferred when an ice cube is placed in a cup of hot tea.

- Disciplinary Core Ideas
- PS3.B Energy is spontaneously transferred out of hotter regions or objects and into colder ones.
- NRC Framework
- PS3.C Patterns of motion, such as a weight bobbing on a spring or a swinging pendulum, can be understood in terms of forces at each instant or in terms of transformation of energy between the motion and one or more forms of stored energy.
