- If an object touches something then one is exposed to that something
- If a spoon is used to stir a liquid then that spoon is touching that liquid
- So, if a spoon is used to stir a liquid, then the spoon is exposed to the liquid

- If a spoon is used to stir a liquid, then the spoon is exposed to the liquid
- Soup is a kind of liquid
- So, if a spoon is used to stir soup, the the spoon is exposed to the soup

- If a spoon is used to stir soup, the the spoon is exposed to the soup
- A metal spoon is used to stir the soup
- So, the metal spoon is exposed to the soup

- The metal spoon is exposed to the soup
- Metal is a thermal / thermal energy conductor
- Therefore, the metal spoon being exposed to the soup is an example of a thermal conductor being exposed to the soup

- If something is heated on a stove, that thing will become hot
- A pan of soup is heated on a stove
- Therefore, the pan of soup will become hot

- The pan of soup will become hot
- A hot substance is a source of heat
- Soup is a kind of substance
- Hence, the pan of soup will become a source of heat

- The metal spoon being exposed to the soup is an example of a thermal conductor being exposed to the soup
- The pan of soup will become a source of heat
- If a thermal conductor is exposed to a source of heat then that conductor will become hot / warm
- Hence, the metal spoon in the soup will become hot

- The metal spoon in the soup will become hot
- If heat is transferred to an object , then the object will get hot
- Hence, heat in the soup transferring to the metal spoon causes the spoon to become hot

Therefore, heat in the soup transferring to the metal spoon causes the spoon to become hot
Question: A student heated a pan of soup on a stove. While stirring the soup with a metal spoon, the student noticed the spoon became very warm. What is the most likely reason the spoon became warm?
Context: - A metal spoon is used to stir the soup 
- If an object touches something then one is exposed to that something 
- Soup is a kind of liquid 
- If heat is transferred to an object , then the object will get hot 
- If a thermal conductor is exposed to a source of heat then that conductor will become hot / warm 
- Soup is a kind of substance 
- A pan of soup is heated on a stove 
- If a spoon is used to stir a liquid then that spoon is touching that liquid 
- Metal is a thermal / thermal energy conductor 
- If something is heated on a stove, that thing will become hot 
- A hot substance is a source of heat
