Density
Density is the mass per unit of volume of a substance. Density is measured in grams per milliliter (g/mL), or grams per centimeters cubed (g/cm3). The density of an object is what causes it to sink or float. If an object has higher density than the liquid it is being placed into, it will sink. If an object has a lesser density than the liquid it is being placed into it will float. For example, the density of water is 1 g/mL. Say that aluminum was being placed into water, the aluminum has a density of 2.7 g/mL. Since the density if the aluminum is greater than water, the aluminum would sink. Say wood is being placed into water, …show more content…
To measure density find the amount of matter that is present in each unit of volume. To find the actual density divide the mass of the object by the volume of the object. Density is actually a ratio of mass to volume. There are multiple ways to increase and decrease density. When you increase density, the object will become more dense and sink more. A way to increase density is keeping the volume of the object and increasing the mass. This keeps the object will have the same amount of space but more matter which causes it sink more. Another way to increase density is keeping the mass and decreasing the volume. This means the object has the same amount of matter but takes up less space. You can do this by scrunching up the object to make it smaller. A third way to increase density is increasing the mass and decreasing the volume. This means that the object has more matter and takes up less space. There are also multiple ways to decrease density. This means by decreasing the density the object will float more rather than sink. One way to decrease density is to can decrease density by keeping the volume and decreasing the mass. The object will take up the …show more content…
Block C is is aluminum with a density of 2.7 g/mL. Block B is an apple with a density of 0.8 g/mL. Block A is wood with a density of 0.4 g/mL. The density of each object was determined by comparing the densities to the density of the liquid the blocks were in (water), comparing it with the other objects densities, and where they were located (sinking or floating) in the water. The density of water is 1 g/mL, and that if an object has a greater density than water it will sink and a lesser density it would float. I concluded that block C had a greater density than all of the other blocks and water because it sunk more than all of the other blocks in water (density of 1 g/mL). The aluminum sunk so it has to have a density greater than 1 g/mL. The object with the greatest density is aluminum, so block C (the most sunken one) has to be aluminum. The density of block B was determined by comparing it with the density of water and the densities of the other blocks. The apple has the second to least density with a density of 0.8 g/mL. Since water has a density of 1 g/mL and the apple has a lesser density than water it has to be one of the floating blocks. But, the apple does have a greater density than the wood. So, it has to be able to float but not as much as the apple. So block B would have to be the apple. The density of block A was determined by comparing it with the density of water and the densities

Block C is is aluminum with a density of 2.7 g/mL. Block B is an apple with a density of 0.8 g/mL. Block A is wood with a density of 0.4 g/mL. The density of each object was determined by comparing the densities to the density of the liquid the blocks were in (water), comparing it with the other objects densities, and where they were located (sinking or floating) in the water. The density of water is 1 g/mL, and that if an object has a greater density than water it will sink and a lesser density it would float. I concluded that block C had a greater density than all of the other blocks and water because it sunk more than all of the other blocks in water (density of 1 g/mL). The aluminum sunk so it has to have a density greater than 1 g/mL. The object with the greatest density is aluminum, so block C (the most sunken one) has to be aluminum. The density of block B was determined by comparing it with the density of water and the densities of the other blocks. The apple has the second to least density with a density of 0.8 g/mL.
