Question
What happens when a cold spoon is placed in hot coffee?
(1 point)
The coffee's molecules have the same kinetic energy as the spoon's molecules, so there is not transfer of thermal energy.
The coffee's molecules have more potential energy, so they transfer thermal energy to the spoon
The spoon's molecules have less kinetic energy, so they transfer thermal energy to the coffee.
The coffee's molecules have more kinetic energy, so they transfer thermal energy to the spoon

The correct answer is:
**The coffee's molecules have more kinetic energy, so they transfer thermal energy to the spoon.**
When a cold spoon is placed in hot coffee, the hotter coffee has molecules that are moving faster (more kinetic energy) compared to the cooler spoon. As a result, thermal energy is transferred from the hot coffee to the cold spoon, causing the spoon to warm up.
**The coffee's molecules have more kinetic energy, so they transfer thermal energy to the spoon.**
