"Anybody knows a good definition of ""phase""?" Popular Answers. 1  A phase, or state of matter, is a domain within a many-body system within which relevant physical properties are uniform. Relevant properties may include chemical composition, stoichiometry, and density, which do not reflect how the components are arranged in space.

- The phase oscillator. A phase oscillator is an oscillator model where we view the state of the system as going around the simplest loop, a unit circle. In a phase oscillator model, the state variable $\theta$ is called the phase of the oscillator. The state space in which the phase $\theta$ lives is the interval $[0, 2\pi]$.

Phases - Gas, liquid and solid Gas, liquid, and solid are known as the three states of matter or material, but each of solid and liquid states may exist in one or more forms. Thus, another term is required to describe the various forms, and the term phase is used.

Definition of Change of state The term phase transition is most commonly used to describe transitions between solid, liquid and gaseous states of matter, and, in rare cases, plasma. A phase of a thermodynamic system and the states of matter have uniform physical properties. During a phase transition of a given medium, certain properties of the medium change, often discontinuously, as a result of the change of some external condition, such as temperature, pressure, or others. For example, a liquid may become gas upon heating

Phases - Gas, liquid and solid Phase is a concept used to explain many physical and chemical changes (reactions). A solid has a definite shape and volume. A liquid has a definite volume but it takes the shape of a container whereas a gas fills the entire volume of a container. You already know that diamond and graphite are solids made up of the element carbon. They are two phases of carbon, but both are solids.

What Is a Phase Change in Science? Quick Answer. A phase change in science refers to any substance that changes from one state to another, with possible states being gas, liquid and solid. Substances typically phase change to the closest related state, such as liquid to solid, but in certain conditions can go from gas to solid or solid to gas. Continue Reading.

Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition A phase is a distinctive form of a substance, and matter can change among the phases. It may take extreme temperature, pressure or energy, but all matter can be changed. There are six distinct changes of phase which happens to different substances at different temperatures. The six changes are: Freezing: the substance changes from a liquid to a solid. Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid.

- Phase space refers to the vector space spanned by combinations of the velocity and position coordinates of a system. In N-body systems, where each body is assumed to be a simple point element, the phase space contains each element's position and momentum/velocity information.

S phase G2 phase a relatively quiescent part of the cell cycle during interphase, lasting from the end of DNA synthesis (the S phase) until the start of cell division (the M phase). M phase the part of the cell cycle during which mitosis occurs; subdivided into prophase, metaphase, anaphase, and telophase.

Phase Diagrams 1 The major features of a phase diagram are phase boundaries and the triple point. 2  Phase diagrams demonstrate the effects of changes in pressure and temperature on the state of matter.  At phase boundaries, two phases of matter coexist (which two depends on the phase transition taking place).

FAQ A: A Phase Change is when physical form changes in relation to temperature. Two examples are when water is heated, it phases to steam, and when water is cooled it phases to solid ice. Q: What is “R” Value. A: R value is a measurement of thermal resistance, the higher the R value the higher the heat resistance.

Advanced Classical Mechanics/Phase Space Advanced Classical Mechanics/Phase Space. Phase space refers to the plotting of both a particle's momentum and position on a two dimensional graph. It also refers to the tracking of N particles in a 2N dimensional space. In many cases, the coordinates used are the canonical variables of Hamiltonian mechanics.

- S phase is the restricted part of the eukaryotic cell cycle during which synthesis of DNA occurs. G2 phase is the period of the cell cycle separating the replication of a cell's chromosomes (S phase) from the following mitosis (M phase). The spindle guides the movement of chromosomes during cell division.
