Final answer:
A cup of hot soup is warmer than a cup of cold soup because it has more heat energy. Metal spoons conduct heat faster than plastic, affecting the soup's temperature if placed in the cup.
Step-by-step explanation:
A cup of hot soup is warmer than a cup of cold soup because it has more heat energy. The temperature difference between the hot and cold soup is a physical property that can be measured and felt. When you are conducting experiments, such as pouring boiling water into two cups and placing different spoons in each, you might notice that a metal spoon heats up more quickly than a plastic spoon.
This is due to the fact that metal is a better conductor of heat than plastic. Energy transfer will be quicker to the metal spoon, which could affect the temperature of the soup if left inside the cup. If more heat is lost to the surroundings like the coffee cup and the environment, the temperature change (ΔT) for the water will be lesser and the calculated heat (q) absorbed or lost by the water will also be less.
