What is an object with high density?
If something is heavy for its size, it has a high density. If an object is light for its size it has a low density. A pebble is heavy for its size, compared to a piece of popcorn which is light for it’s size.
What are two objects that have density?
Everyday Density Examples
- In an oil spill in the ocean, the oil rises to the top because it is less dense than water, creating an oil slick on the surface of the ocean.
- A Styrofoam cup is less dense than a ceramic cup, so the Styrofoam cup will float in water and the ceramic cup will sink.
What are examples of dense objects?
Examples of dense materials include iron, lead, or platinum. Examples of sparse materials include Styrofoam, glass, soft woods like bamboo, or light metals like aluminum.
What objects are density?
Densities of Common Substances
|Material||Density (g/cm3)||State of Matter|
|water at 20°C||0.998||liquid|
|water at 4°C||1.000||liquid|
How can you reduce the density of an object?
Increasing the pressure on an object decreases the volume of the object and thus increases its density. Increasing the temperature of a substance (with a few exceptions) decreases its density by increasing its volume.
Does higher density mean heavier?
Density is by definition, the amount of mass per unit volume. Density tells scientists how “heavy” a substance is. If a substance has a higher density, it is heavier. Likewise a lighter density means it is much lighter.
What is density example?
Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units).
What are three examples of density?
Examples of Density:
- Oil and Water Don’t Mix. It’s a known fact that oil and water don’t mix, but what many people may not know is that the density of oil is what makes it float on top of water.
- Helium Balloons.
- Archimedes and Eureka!
What has a density of 1?

What are two ways to increase density?
What can change density: 1) Adding or removing mass but not changing the volume. Increasing or decreasing temperature changes the volume but not the mass. Increasing or decreasing pressure will change the volume but not the mass.
Does density affect weight?
Density is an intensive physical property whereas weight is an extensive property. Density changes when the pressure and temperature of an object changes, whereas the weight changes when the mass of an object and gravity changes. Gravity does not affect density whereas on the other hand gravity directly affects weight.
How do you determine high density?
Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples’ volume.
What is an example of a dense object?
Examples of dense materials include iron, lead, or platinum. Many kinds of metal and rock are highly dense. Dense materials are more likely to ‘feel’ heavy or hard. Although a sparse material (sparse is the opposite of dense) can feel heavy if it’s really big.
Why do dense objects sink?
Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. Hollow things often float too as air is less dense than water. This is partly why huge heavy ships float.
What are dense objects?
Density is a way to measure how tightly packed an object is. Denser objects have less empty space in them, they are less holey. The density of an object is often measured in grams per milliliter.
What is a low density material?
LDPE (low density polyethylene) is a soft, flexible, lightweight plastic material. LDPE is noted for its low temperature flexibility, toughness, and corrosion resistance.
