Item NG022003: When water that is 40ºF is poured into a cup that is 70ºF, thermal energy is transferred from the cup to the water until they reach the same temperature.
The temperature of a plastic cup is 70ºF. It is filled with water that is 40ºF. Which of the following describes how thermal energy is transferred?
- Thermal energy is transferred from the water to the cup until they are both at 45ºF.
- Thermal energy is transferred from the cup to the water until they are both at 45ºF.
- Thermal energy is transferred from the cup to the water until the cup is at 60ºF and the water is at 50ºF.
- No thermal energy is transferred between the cup and the water, so the cup will stay at 70ºF and the water will stay at 40ºF.
