Buoyancy PreLab

Which is a concept that will be investigated throught the Buoyancy Lab? Click all that apply.

• How does object mass affect buoyancy?

• How does object volume and fluid volume affect buoyancy?

• Determining the density of various objects.

• Can we predict buoyant force when object volume is known?

Select the lab materials that will be used throughout the Buoyancy Lab. ​ ​ (a)   ​​ (b)   ​ ​ (c)  

• set of weights
• spring scale
• graduated cylinder
• triple beam balance
• large beaker
• electronic scale
• thermometer

How will you accurately determine the volume of an irregularly shaped object using the water displacement method?

• By measuring the object's height, width, and length and using the volume formula for a rectangular prism.
  

• By submerging the object in water and measuring the increase in water level.

• By weighing the object and using the density of water to find the volume.
  

• By calculating the surface area of the object and dividing it by the density of water.

Can we predict the buoyant force when an object's volume is known?

• Yes

• No

• Maybe

• Not sure

What is the density of water?

• 1 g/mL

• 10 g/mL

• 100 g

• 10 mL

What will the density of water be used for in Part 1?

• To determine the volume of water displaced.

• To confirm the mass or the weight used.

• To determine the mass of water displaced.

• To determine the force of gravity.

The upward force exerted by liquids is called

• buoyancy

• density

• floating

• gravity
