Question

Two friends bought phones that cost different amounts but had identical batteries. After using the phones for a while, both friends had to turn them off to let the batteries cool. This table shows how the temperature of each battery changed over 5minutes.
Battery	Initial temperature (°C)	Final temperature (°C)
Battery in the less expensive phone	38	24
Battery in the more expensive phone	38	27

during this time,thermal energy was transferred from ? to ?
A. each battery...the surroundings
B. the surroundings...each battery

GPT-4o mini · Answer

The correct answer is A: **each battery...the surroundings**. This is because the temperature of both batteries decreased over time, indicating that thermal energy was transferred from the batteries to the surroundings (i.e., the environment), causing the batteries to cool down.
