I challenge you to create two dishes. One that involves a physical change and one that involves a chemical change. If I'm not satisfied, then your cafe will be shut down.
Once there was a small cafe that was owned by a very talented chef who was dedicated to his work. However, the restaurant was always short of money. So he decided to bring in a food critic to bring in some publicity.
Let's see whether this is worth my time. If I were you, I would be thinking about finding a new job.
How about we wait until you actually taste the food. I'm sure you won't be disappointed.
A few days later. . .
Let's start with the physical changes dish. A physical change is a change in appearance of an object and not its identity
The dish for the physical changes are macaroni salad. The macaroni was boiled which caused it soften however it is till macaroni. Same goes for the vegetables that were chopped but they are still vegetables.
Alright, that macaroni salad was okay but there is no way you are going to succeed in making the chemical change dish. A chemical change is the formation of a whole new substance with different properties than the former substance.
Wow! This cafe is phenomenal! People will be lining the streets for the food!
The dish for the chemical changes is a rich, chocolate cake. The heat from the oven causes the baking powder in the cake to produce tiny gas bubbles which gives the cake its fluffiness. The heat also causes the protein from the egg to change and make the cake firm.
