Conversation

Have you ever thought about how density affects the way things float in water?

Yeah, it’s fascinating! I learned that denser objects sink while lighter ones float.

Exactly! It’s all about the mass compared to the volume.

Right, and that’s why ships can float even though they’re so heavy.

Root Explanation

Density → It is formed from "densitas" (from Latin, meaning thickness or compactness) and the suffix "-ity" (meaning quality or state of). The word "density" refers to the quality of being thick or compact, often used to describe how much mass is contained in a given volume.

Memory Tip

Think of 'thickness' ('densitas') to remember that 'density' refers to how compact something is.
