Question

the table shows the densities of four solid objects in grams per milliliter at 25°c.

an apple cider vinegar sample has a density of 1.02 grams per milliliter at 25°c. use the density values to predict which objects will float or sink when placed in the apple cider vinegar sample.

Explanation:

Step1: Recall the density rule

Objects with density less than liquid float; those with higher density sink.

Step2: Compare object densities with vinegar density (1.02 g/mL)

• Foam ball: \(0.44\lt1.02\), so it floats.
• Wooden spoon: \(0.63\lt1.02\), so it floats.
• Marble tile: \(2.80\gt1.02\), so it sinks.
• Tin cube: \(7.28\gt1.02\), so it sinks.

Answer:

• Floats in the apple cider vinegar sample: foam ball, wooden spoon
• Sinks in the apple cider vinegar sample: marble tile, tin cube
