Question

the table shows the densities of four solid objects in grams per milliliter at 25°c.
object | density (g/ml)
foam lid | 0.44
gold ring | 19.30
six - sided die | 1.20
wooden bead | 0.71
a corn syrup sample has a density of 1.43 grams per milliliter at 25°c. use the density values to predict which objects will float or sink when placed in the corn syrup sample.
wooden bead gold ring foam lid six - sided die
floats in the corn syrup sample
sinks in the corn syrup sample

Explanation:

Step1: Recall float/sink rule

An object floats if its density is less than the fluid's density, sinks if greater.

Step2: Compare each object's density to 1.43 g/mL

• Foam lid: $0.44 < 1.43$
• Wooden bead: $0.71 < 1.43$
• Six-sided die: $1.20 < 1.43$
• Gold ring: $19.30 > 1.43$

Answer:

Floats in the corn syrup sample:

foam lid, wooden bead, six-sided die

Sinks in the corn syrup sample:

gold ring
