DENSITY 1

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What is the density of a substance if its mass is 50g and its volume is 10 cm³?

Back

5 g/cm³

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

What happens to the density of a substance when it is heated?

Back

Generally, the density decreases as the substance expands.

Front

What is the density of water at 4°C?

Back

1 g/cm³

Front

How does the density of gases compare to liquids and solids?

Back

Gases are generally much less dense than liquids and solids.

Front

What is the significance of a substance's density in real-world applications?

Back

Density is crucial in determining whether objects will float or sink, and in material selection.

Front

If a substance has a density of 2 g/cm³, what does this imply about its mass and volume?

Back

For every 1 cm³ of this substance, it has a mass of 2 grams.

Front

What is the unit of density in the metric system?

Back

g/cm³ (grams per cubic centimeter) or kg/m³ (kilograms per cubic meter)

Front

How can you determine if an object will float in water?

Back

If the object's density is less than 1 g/cm³, it will float.
