0 K on the Kelvin scale, it is the theoretical minimum possible temperature, at which an object would have the lowest possible kinetic energy.
A solid that is made up of atoms that have no particular organization.
A unit of distance equal to ten to the power of negative ten (10-10) meters.
The smallest unit of elements, made up of electrons surrounding the nucleus of protons and neutrons.
A phase transition in which a liquid rapidly changes to a gas.
The temperature at which a liquid changes to gas.
The random movement of particles in a liquid or gas.
Takes place in definite proportions, and results in the formation of new compounds and/or elements. It involves the breaking of bonds, and the formation of new ones.
Qualities whose identification requires a change in the substance's structure. They describe how a substance will behave in a chemical reaction.
The ability to reduce the volume of a substance.
A phase change in which a substance transitions from the gas phase, to the liquid phase.
A solid formed by particles that are arranged in an orderly repeating pattern.
When particles spread out to evenly fill a space.
The process in which a liquid changes phase into a gas. It only takes place at the surface of a liquid.
The process in which a liquid undergoes a phase change to become a solid.
The temperature at which a substance transitions from a liquid to a solid.
A state of matter in which the particles move about freely, with no structure. It will always fill the container it is in, assuming its size and shape.
The pressure caused by gas particles hitting the sides of the container surrounding them.
The basic unit of measurement on the Kelvin scale, which is the unit of measurement in the metric system.
The energy of an object caused by its motion.
Particles are in constant motion. In a solid they may just vibrate next to each other, but in a liquid or gas they travel much faster.
A state of matter which is characterized as having definite volume, but no definite shape.
The process in which a solid changes phases into a liquid.
The temperature at which a substance transitions from a solid to a liquid.
A unit of distance equal to ten to the power of negative nine (10-9) meters.
The different states of matter, such as solids, liquids, or gasses.
Qualities of a substance that can be observed and measured without changing the identity of the substance.
A state of matter similar to gas, but in which the particles are moving at much greater speeds, and are electrically charged.
A state of matter in which the object has a definite shape and volume.
The process in which a solid transitions directly into a gas, without becoming a liquid.
A measure of the average kinetic energy of the particles in a substance.
The thickness of a liquid.
