Question

You are provided with the following:-

• A block of wood
• A spring balance
• Thin thread
• Overflow can
• A small measuring cylinder
• Some liquid

  With the aid of a labeled diagram an experiment to the law of floatation

Answer 1

• Measure the weight of blocks of wood in air
• Fill the overflow can with the liquid and let the excess liquid flow out then place an empty measuring cylinder below the spout
• Place the block of wood in the overflow can and measure the volume of the displaced liquid inside the cylinder
• Using the density of the liquid, calculate the mass and then weight of the displaced liquid
• Compare the weight of the block with the value of the weight of the displaced liquid
