Which of the following is an example of the Conservation of Mass?
Eating a cake
Baking a cake
Mixing a cake
Mixing a cake is an example of the Conservation of Mass.
Mixing a cake is an example of the Conservation of Mass. The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction. When you mix a cake batter, the mass of the ingredients remains constant throughout the process.
The Conservation of Mass is a fundamental principle in chemistry that states that mass is neither created nor destroyed during a chemical reaction. In other words, the total mass of the substances involved in a chemical reaction remains constant.
When considering the examples provided, we can analyze each one to determine if it adheres to the principle of the Conservation of Mass:
1. Eating a cake: This activity does not represent a chemical reaction but rather a physical change in the state of the cake. The cake is broken down into smaller pieces and then consumed, but the total mass of the cake remains the same. Therefore, this is not an example of the Conservation of Mass.
2. Baking a cake: During the process of baking a cake, various ingredients (such as flour, sugar, eggs, butter) are combined and chemical reactions occur that transform the mixture into a cake. While some water and other volatile compounds may evaporate during the baking process, the total mass of the cake ingredients does not change significantly. Thus, as long as the cake ingredients are measured accurately, this can be considered an example that follows the Conservation of Mass.
3. Mixing a cake: This statement is somewhat ambiguous since it does not specify what is being mixed. However, similar to baking a cake, if we assume that multiple cake ingredients are being mixed together (i.e., flour, sugar, eggs, butter), this can also be considered an example that adheres to the Conservation of Mass, as the total mass of the ingredients remains constant.
In summary, both baking a cake and mixing a cake can be seen as examples of the Conservation of Mass.
