Measuring the density of eggs Use the following equipment: a beaker, salt, thin wall test tube with flat and thick bottom, ruler, water, thin wooden stick Measure the density of egg and write the expression of density with the measured physical quantity

Measuring the density of eggs Use the following equipment: a beaker, salt, thin wall test tube with flat and thick bottom, ruler, water, thin wooden stick Measure the density of egg and write the expression of density with the measured physical quantity

Measure the bottom diameter D of the beaker with a scale, and calculate the bottom area s = Wu (D / 2) 2 (surface square). Then add water to the beaker and measure its height H1 with a scale. Then put the egg into the beaker with water, and measure its height H2. At this time, the volume of the egg v = (h1-h2) XS can be calculated, and gradually add salt into the water until the egg floats,
