Question

reflections and conclusions

1. ship 1 has a density of 0.98 g/ml, and ship 2 has a density of 1.03 g/ml. the density of fresh water is 1 g/ml, and the density of salt water is 1.025 g/ml. which ship will float in both fresh water and salt water? why?

Explanation:

Step1: Recall buoyancy principle

An object floats when its density is less than the density of the fluid.

Step2: Analyze Ship 1

The density of Ship 1 is $0.98\ g/mL$. The density of fresh - water is $1\ g/mL$ and the density of salt - water is $1.025\ g/mL$. Since $0.98\ g/mL<1\ g/mL$ and $0.98\ g/mL < 1.025\ g/mL$, Ship 1 will float in both fresh - water and salt - water.

Step3: Analyze Ship 2

The density of Ship 2 is $1.03\ g/mL$. Since $1.03\ g/mL>1\ g/mL$, Ship 2 will sink in fresh - water. Since $1.03\ g/mL>1.025\ g/mL$, Ship 2 will sink in salt - water.

Answer:

Ship 1 will float in both fresh water and salt water.
