Relative Density

Front

What is relative density?

Back

Relative density is the ability of an object to sink or float in a fluid compared to the density of that fluid.

Front

How do you determine if an object will float or sink in water?

Back

An object will float if its relative density is less than that of water, and it will sink if its relative density is greater.

Front

What is the relationship between mass and volume in determining density?

Back

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

Front

If an object has a relative density of 0.8, will it float or sink in water?

Back

It will float because its relative density is less than that of water (1.0).

Front

What happens to the relative density of an object if you increase its mass while keeping its volume the same?

Back

The relative density increases because density is mass divided by volume.

Front

What is the order of liquids from most dense to least dense if given the densities: 1.0, 0.8, 0.6, 0.9?

Back

The order is 1.0, 0.9, 0.8, 0.6.

Front

What does it mean if an object is less dense than water?

Back

It means the object will float on the surface of the water.

Front

If sand is more dense than water, what can we infer about its behavior in water?

Back

Sand will sink in water because it is more dense.

Front

What is the effect of temperature on the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases.

Front

How can you compare the densities of two objects?

Back

You can compare their relative densities by seeing which one sinks or floats in a fluid.
