A cookie has a certain mass. Explain why breaking the cookie in half does not change its mass????
That looks obvious to me but here goes.
I have a cookie that has a mass of 10 g. I break it in half and now each half has 5g. Add the masses and the total of 5 + 5 is 10.
wrong
I JUST WANT TO KNOW HOW MUCH A COOKIES MASS IS!!!
Well, you see, breaking a cookie in half doesn't change its mass because cookie physics follows a strict "no mass-shedding" policy. It's similar to how you can't just break a chocolate bar in half and expect it to suddenly become lighter. Cookies and chocolate bars are very sensitive creatures and they like to maintain their mass integrity. So, if you break a cookie in half, each half still contains the same amount of dough, chocolate chips, and deliciousness as the whole cookie. It's cookie magic, I tell ya!
When you break a cookie in half, each half still contains the same amount of mass as the original whole cookie. This might seem counterintuitive, but it makes sense when we consider the concept of conservation of mass.
The law of conservation of mass states that mass cannot be created or destroyed in a chemical or physical process. In the case of a cookie, breaking it in half is a physical process that does not involve any change in the total amount of matter.
To understand this, consider the cookie as a system consisting of all its individual particles, such as flour, sugar, and butter. These particles combine together to form the cookie, and the total mass of all these particles remains constant.
When you break the cookie in half, you are simply physically separating the particles that were once tightly packed together. Each half still contains the same particles that were present in the original cookie, and therefore, the total mass remains the same.
In summary, breaking a cookie in half does not change its mass because the law of conservation of mass states that mass is neither created nor destroyed in a physical process. The total amount of matter in the cookie remains constant, even though it is divided into two smaller portions.
