Final answer:
The correct order from the object with the smallest mass to the largest is: pencil (5 grams), cup (150 grams), teddy bear (225 grams), and book (500 grams). Density cannot be ranked with the given information, which only provides mass, not volume. The gram is a suitable unit for measuring small objects like these.
Step-by-step explanation:
To list the objects from the smallest to the largest mass, we should compare the mass of each object and arrange them accordingly. Given the masses: teddy bear 225 grams, pencil 5 grams, book 500 grams, cup 150 grams, we can determine the correct order.
The correct order, starting with the object that has the smallest mass, is as follows:
- Pencil: 5 grams
- Cup: 150 grams
- Teddy bear: 225 grams
- Book: 500 grams
This sequence shows that the pencil has the smallest mass, and the book has the largest mass out of the items listed.
When we rank the densities of the objects listed, we must note that density is mass per unit volume, and since we aren't provided with the volumes of these objects, we cannot calculate or rank their densities based on the information given.
The mass of one object can be less than, greater than, or equal to the mass of another. For example, the mass of the teddy bear is greater than that of the cup.
Macroscopic objects such as these are typically measured in grams or kilograms. Grams are suitable for these items as they are too large for milligrams and too small for kilograms.
For example, scientists might use grams to measure something like the weight of five pennies, which is too light for kilograms but too heavy for milligrams.
