Question

if a hot metal spoon is placed into a cup of cold soup, which statement best predicts what will happen to the energy?
energy will transfer from the soup to the spoon, making the spoon hotter.
energy will be destroyed in both the spoon and the soup until they are the same temperature.
energy will transfer from the spoon to the soup, and the total energy of the system will stay the same.
the spoon will create new energy to make the soup hotter.

Explanation:

Step1: Analyze heat transfer principle

Heat (energy) transfers from a hotter object to a colder one. Here, the hot metal spoon (initially hotter than cold soup) will transfer energy to the soup.

Step2: Check energy conservation

Energy is conserved. It doesn't get destroyed (so the option "Energy will be destroyed in both the spoon and the soup until they are the same temperature" is wrong). Also, energy isn't created (so "The spoon will create new energy to make the soup hotter" is wrong). And the total energy of the system (spoon + soup) remains the same as energy just transfers. The correct transfer is from the hotter (initially the spoon) to the colder (soup), so energy transfers from the spoon to the soup until thermal equilibrium (same temperature) is reached.

Answer:

Energy will transfer from the spoon to the soup, and the total energy of the system will stay the same.
