Density

Front

What is the formula to calculate density?

Back

Density = Mass / Volume

Front

What happens to an object with a density greater than that of water when placed in water?

Back

It sinks.

Front

What happens to an object with a density less than that of water when placed in water?

Back

It floats.

Front

If an object has a mass of 10 grams and a volume of 2 ml, what is its density?

Back

5 g/ml

Front

What is the unit of measurement for density in the metric system?

Back

g/ml or kg/m³

Front

How does the density of a substance change with temperature?

Back

Generally, density decreases as temperature increases due to expansion.

Front

What is the relationship between mass and density?

Back

Density is mass per unit volume; if mass increases while volume remains constant, density increases.

Front

Why do objects with the same volume have different densities?

Back

Because they have different masses.

Front

What is the density of pure water at 4°C?

Back

1 g/ml

Front

How does the density of a solution compare to that of its solute and solvent?

Back

The density of a solution is typically between the densities of the solute and solvent.
