Question

Differentiate between determination of density of regular

solids and determination of irregular solids. (​

Answer 1

Answer:

Explanation:

1. Method 1: A regular shaped object

• Use a ruler to measure the length (l), width (w) and height (h) of the object.

• Place the object on the top pan balance and measure its mass.

• Calculate the volume of the cube using (l x w x h).

• Use the measurements to calculate the density of the object.

  2.Method 2: An irregular shaped object

• Place the object on the top pan balance and measure its mass.

• Fill a measuring cylinder so that there is enough water to cover the object when it is placed inside the cylinder. Take the reading of the volume.

• Carefully lower the object into the cylinder.

• Take the new reading of the volume. Subtract the original reading to obtain the volume of the object.

Method 1: For density of regular solid

• Use a ruler to measure the length (l), width (w) and height (h) of the object.
• Place the object on the top pan balance and measure its mass.
• Calculate the volume of the cube using (l×w×h) .
• Use the measurements to calculate the density of the object.

Method 2: For density of irregular solid

• Place the object on the top pan balance and measure its mass.
• Fill a measuring cylinder so that there is enough water to cover the object when it is placed inside the cylinder. Take the reading of the volume.
• Carefully lower the object into the cylinder.
• Take the new reading of the volume. Subtract the original reading to obtain the volume of the object.
• Use the measurements to calculate the density of the stone.
