## What causes density to change?

Density is the amount of mass located in a specific volume. The density of an object can change if either the mass or volume of the object is changed. If an object is more dense than water, it will sink; if it is less dense than water, it will float.

## What would increase density?

You can use this density variation in water to increase its density. However, temperature fluctuates naturally, so if you wish to increase the density permanently, you can add salt to the water. This increases the water’s mass without increasing its volume. Thus, its density increases.

## What determines density?

Density is a characteristic property of a substance. The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.

## How do you explain density to a 4 year old?

Density for Kids Density is a measure of how close together these pieces are. If they are close together, the object is dense. If the pieces are far apart, the object is less dense as their is more space for air.

## What are two facts about density?

Density, the weight of an object divided by its volume, is a property of all matter, including solids, liquids and gases. The value of an object’s density depends on what it’s made of as well as its temperature; for example, lead weights are denser than feathers, and cold air is denser than hot air.

## What has low density?

Gases have a very low density because their particles are very far apart; for example, air has a density of 0.0013 g/cm3.

## What liquids have low density?

Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids. The same amount of two different liquids you used in the container will have different densities because they have different masses.
