Which object will sink in freshwater, which has a density of 1.0 g/cm³?

An object sinks in freshwater if its density is greater than the density of freshwater (1.0 g/cm³).
Explanation

Understanding the Problem The problem asks us to determine which object will sink in freshwater, given that freshwater has a density of 1.0 g/cm³. An object will sink if its density is greater than the density of the fluid it is placed in.

Determining the Condition for Sinking To determine if an object will sink, we need to compare its density to the density of freshwater, which is 1.0 g/cm³.

Comparing Densities If the object's density is greater than 1.0 g/cm³, it will sink. If it is less than 1.0 g/cm³, it will float. If it is equal to 1.0 g/cm³, it will be neutrally buoyant.


Examples
Imagine you're building a boat. Understanding density helps you choose materials that will float. If the materials you choose are denser than water, your boat will sink! This principle applies to many real-world scenarios, from designing ships to understanding why some objects float and others don't.

An object will sink in freshwater if its density is greater than 1.0 g/cm³. For instance, a rock, with a density around 2.5 g/cm³, will sink, while a plastic bottle with a density around 0.9 g/cm³ will float. This basic understanding of density and buoyancy is essential in physics.
