Question

25) If an object’s density is greater than 1.00 g/mL, it will ______________ in water.

Answer 1

Answer:

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
