Answer
Explanation:
Step1: Answer for 4A
Mass alone does not determine floating - sinking. A large - mass object can float if it has large volume (low density). For example, a large ship made of steel has a large mass but floats because its shape gives it a large volume.
Step2: Answer for 4B
Volume alone does not determine floating - sinking. A small - volume object can sink if it has high mass (high density). For example, a small gold coin has a small volume but sinks in water.
Step3: Answer for 4C
For floating objects, the ratio of mass to volume (density) is less than the density of the liquid (water in this case).
Step4: Answer for 4D
For sinking objects, the ratio of mass to volume (density) is greater than the density of the liquid (water in this case).
Step5: Answer for 6A
The density of floating objects is less than 1.0 g/mL (the density of water).
Step6: Answer for 6B
The density of sinking objects is greater than 1.0 g/mL (the density of water).
Step7: Answer for 7
Calculate the density of the object using the formula $\rho=\frac{m}{V}$ (where $\rho$ is density, $m$ is mass, and $V$ is volume). If $\rho< 1.0$ g/mL, the object will float in water; if $\rho > 1.0$ g/mL, the object will sink in water.
Answer:
4A. No. Explanation: Mass alone does not determine floating - sinking. A large - mass object can float if it has large volume (low density). 4B. No. Explanation: Volume alone does not determine floating - sinking. A small - volume object can sink if it has high mass (high density). 4C. For floating objects, the ratio of mass to volume (density) is less than the density of water. 4D. For sinking objects, the ratio of mass to volume (density) is greater than the density of water. 6A. The density of floating objects is less than 1.0 g/mL. 6B. The density of sinking objects is greater than 1.0 g/mL. 7. Calculate the density of the object using $\rho=\frac{m}{V}$. If $\rho<1.0$ g/mL, it will float; if $\rho > 1.0$ g/mL, it will sink.
