Question

use the following data to help you answer the questions.
substance mass (g) volume (cm³) density (g/cm³)
oak wood 10 11.7 0.9
beeswax 10 10 1.0
ebony wood 10 9.1 1.1
aluminum 10 3.7 2.7

1. the density of the substances differs because the mass of each differs. true false
2. water has a density of 1.0 g/ml. all of the substances in the data table will sink in water. true false
3. the greater the volume of a substance, the greater the density. true false

Explanation:

Step1: Analyze statement 1

The mass of each substance in the table is 10g, but densities are different due to different volumes. So the statement "The density of the substances differs because the mass of each differs" is false.

Step2: Analyze statement 2

Oak - wood has a density of 0.9 g/cm³ which is less than the density of water (1.0 g/mL), so it will float. Not all substances will sink. So the statement is false.

Step3: Analyze statement 3

From the table, oak - wood has a larger volume (11.7 cm³) than ebony - wood (9.1 cm³) but a lower density (0.9 g/cm³ vs 1.1 g/cm³). So density is not directly proportional to volume. The statement is false.

Answer:

1. False
2. False
3. False
