If your cereal, bowl, and metal spoon all start at room temperature and the milk is cold from the fridge, choose all of the energy transfers that will take place.

Question

Question 10 options:

Energy moves from cereal to milk.

Energy moves from spoon to milk .

Energy moves from bowl to milk .

Energy moves from milk to bowl.

Energy moves from milk to bowl.

Energy moves from milk to cereal.

Answer 1

In this scenario, the cold milk will draw heat (thermal energy) from the warmer objects. Here are the correct energy transfers that will take place:

1. Energy moves from cereal to milk. - The cereal is at room temperature and will transfer some of its thermal energy to the cold milk, warming up the milk slightly.

2. Energy moves from spoon to milk. - The metal spoon, being warmer than the cold milk, will also transfer some of its thermal energy to the milk.

3. Energy moves from bowl to milk. - If the bowl is at room temperature, it will similarly transfer some thermal energy to the cold milk.

So, the correct transfers are:

• Energy moves from cereal to milk.
• Energy moves from spoon to milk.
• Energy moves from bowl to milk.

The following transfers do not occur:

• Energy moves from milk to bowl. - The milk is cold, so it does not transfer energy to the warmer bowl.
• Energy moves from milk to cereal. - The milk, being colder, does not transfer energy to the warmer cereal.

Therefore, the answer is the first three options.
