Answer

Explanation:

Step1: Analyze statement 1

Density is mass per unit volume ($\rho=\frac{m}{V}$). Here mass is same for all substances (10 g), so density differences are due to volume differences, not mass differences. So statement 1 is false.

Step2: Analyze statement 2

Oak - wood density ($0.9\ g/cm^{3}$) is less than water density ($1.0\ g/mL = 1.0\ g/cm^{3}$), so oak - wood will float. Not all substances will sink. So statement 2 is false.

Step3: Analyze statement 3

From the data, oak - wood has larger volume ($11.7\ cm^{3}$) but lower density ($0.9\ g/cm^{3}$) compared to ebony - wood with smaller volume ($9.1\ cm^{3}$) and higher density ($1.1\ g/cm^{3}$). So density is not directly proportional to volume. So statement 3 is false.

Answer:

  1. False
  2. False
  3. False
