motion of molecules
Question | Answer |
---|---|
Condensation | the conversion of a vapor or gas to a liquid |
Expansion | the action of becoming larger or more extensive |
Molecule | a group of atoms bonded together, representing the smallest fundamental unit |
Motion | the action or process of moving or being moved |
Pressure | continuous physical force exerted on or against an object by something in contact with it. |
Temperature | the degree or intensity of heat present in a substance or object, |
Volume | the amount of space that a substance or object occupies, or that is enclosed within a container, |
Density | the degree of compactness of a substance |
Gas | a substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume |
Liquid | a substance that flows freely but is of constant volume, having a consistency like that of water or oil |
Solid | firm and stable in shape; not liquid or fluid. |
Speed | the rate at which someone or something is able to move or operate |
States of Matter | one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma |
Kinetic theory of matter | says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion |
Melting | make or become liquefied by heat. Solid to liquid state |
Freezing–(of a liquid) | be turned into ice or another solid as a result of extreme cold.: |
evaporation/vaporization\boiling | the process of turning from liquid into vapor |
Sublimation | is the transition of a substance directly from a solid state to a gas state |
Deposition | phase transition in which gas transforms into solid without passing through the liquid phase. |
Conduction | the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material |
Convection | the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in the transfer of heat |
radiation | is the emission or transmission of energy in the form of waves or particles through space or through a material medium |
