Final answer:
The energy redistribution when a spoon is placed in hot coffee is through conduction, where heat is transferred through direct contact between objects.
Step-by-step explanation:
When a spoon at room temperature is placed in a cup of hot coffee, energy is redistributed through a process called conduction.
Conduction is the transfer of heat through direct contact between objects or substances. In this case, the hot coffee transfers heat to the spoon.
This transfer of heat causes the temperature of the spoon to increase, making it feel warm to the touch.
