Front

What can be inferred if a ping pong ball is floating in water?

Back

The ping pong ball is less dense than the water.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in.

Front

How is density calculated?

Back

Density is calculated by dividing mass by volume (Density = Mass/Volume).

Front

What are the three main phases of matter?

Back

Solid, liquid, and gas.

Front

What happens to the density of most substances when they are heated?

Back

Most substances expand and become less dense when heated.

Front

What is the significance of the triple beam balance in measuring mass?

Back

It provides a precise measurement of mass in grams.
