Matter - Science Language
The layers of air that surround Earth. The most dense atmospheric layers are closer to Earth and the least dense layers are far away from Earth.
The smallest particle of a chemical element which has all the properties of that element.
The solid outermost layer of Earth.
A comparison of the mass of a substance with its volume. Mathematically, density is calculated as: An object or liquid tends to sink in a liquid with less density than the object.
The process of matter spreading out evenly from its source. An example of diffusion is when perfume is sprayed and eventually is smelled throughout a room.
The amount of motion of a particle.
The least dense form of matter for a given substance. Particles in a gas are moving rapidly and tend to be quite far apart. Particles move freely and have no definite shape.
A transfer of kinetic energy or motion.
The form of matter that tends to flow freely. Typically liquids are capable of taking on the shape of the container that they are placed within. Particles are in constant motion but are closer together than the same particles in a gas form.
A measure of the amount of matter in an object. Mass is usually measured in grams.
Anything that has mass and takes up space.
A larger or smaller representation of an item.
A substance that occurs when two or more atoms are chemically combined. It is the smallest form of such a chemical combination.
A small piece of something. Typically used to represent a small part of matter.
The most dense form of matter for any substance. Solids generally have a fixed shape. The particles within them vibrate constantly, but do not allow the solid to change shape.
A measure of the amount of kinetic energy of a particle. Objects with a high amount motion have a higher temperature than those with a lower amount of motion.
The amount of space taken up by a substance. Volume is generally stated as cubic meters m3, liters or a variation of one of these.
