When you double the amount of coffee, you also double the
The amount of coffee will increase its volume, but its density will remain the same. However, if you add double the amount of water to double the amount of coffee, then you will also double the total volume of the coffee and water mixture.
To answer this question, we need to understand what "double" means in this context. When we say we are doubling an amount of something, it means we are multiplying that amount by 2.
In this case, we are doubling the amount of coffee. So if we have an initial amount of coffee, let's say x, then doubling that amount means multiplying it by 2. Therefore, the doubled amount of coffee would be 2x.
Now, let's consider what is being doubled. The question states that when you double the amount of coffee, you also double something else. To find out what that "something else" is, we need more information. Without that information, we cannot determine what gets doubled along with the amount of coffee.
