25) if an object’s density is greater than 1.00 g/ml, it will in water.

a) sink
b) float


if an object’s density is less than 1.00 g/ml, it will in water.

a) sink
b) float


26) what is the density of a rock if it has a mass of 50 g and a volume of 10 ml? (you must show your work! )

1- Option A = Sink

2- Option B = Float

Explanation:

1- If an object’s density is greater than 1.00 g/mL, it will sink in water.

For example, the density of aluminum is 2.7g/cm³. That is why it will sink in water.

2- If an object’s density is less than 1.00 g/mL, it will float in water.

For example, the density of oak is 0.7 g/cm³. That is why oak will float in water.

3-  Given data:

Mass, m = 50 g  

Volume, v = 10 cm3 ( 1ml = 1cm3)

Formula of density :          

Density = mass/ volume

          d = m/v

          d = 50g/10cm3

          d = 5 g/cm3

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the dissolution of polymer can be thermodynamically described in 2 steps.
