Some cooked food float on soup?

Cooked food that floats on soup typically has a lower density than the soup itself. Density is the mass of an object divided by its volume. Therefore, objects with a lower density are less dense than the surrounding liquid and will float.

Common cooked foods that tend to float on soup include:

1. Dumplings: Dumplings are made from a dough that is typically composed of flour, baking powder, salt, and water. This dough has a relatively low density and will often float on the surface of the soup.

2. Wontons: Wontons are another type of dumpling that is popular in Chinese cuisine. They are typically made from a wheat flour dough and filled with a variety of ingredients, such as pork, shrimp, or vegetables. Wontons also have a low density and will often float on soup.

3. Matzo balls: Matzo balls are a type of dumpling that is popular in Jewish cuisine. They are made from ground matzo meal and egg and have a slightly bland flavor. Matzo balls have a lower density than water and are another example of food that floats on soup.

4. Noodles: Noodles are typically made from wheat flour and are a common ingredient in soups. Although some noodles may absorb liquid and sink to the bottom of the soup, others (such as egg noodles) may have a lower density and remain floating.

It's worth noting that some foods may initially float on soup due to trapped air or gas pockets, but as they absorb liquid, they may eventually sink. Additionally, the temperature of the soup and the specific ingredients used can influence whether a particular food floats or sinks.
