================================================================================================================================== Hi, Heat flow from a hot to a cold body occurs spontaneously. This flow of energy can be harnessed and converted into useful work by means of a [|heat engine]. The [|second law of thermodynamics] ensures that heat flow from a cold to a hot body never occurs, although external work can be employed to "[|pump]" thermal energy from cold to hot. Heat can be measured with a [|calorimeter], or determined indirectly by calculations based on other quantities, relying for instance on the the [|first law of thermodynamics]. [|Heat transfer] can occur in a variety of ways: by [|conduction], radiation, [|convection], [|net mass transfer], friction or viscosity, and by chemical dissipation. In physics, especially in [|calorimetry], and in [|meteorology], the concepts of //[|latent heat]// and of //[|sensible heat]// are used. Latent heat is associated with phase changes, while sensible heat is associated with temperature change, and is equivalent to [|thermal energy] when stored in an object or system. In common usage, the noun //heat// has a broader meaning, and can refer to [|temperature] or to the sensation felt when touching or being close to a high-temperature object.
 * Heat** is [|energy] transferred from one [|system] to another by thermal interaction. In contrast to [|work], heat is always accompanied by a transfer of entropy. Heat is a characteristic of [|macroscopic] objects and systems, but its origin and properties can be understood in terms of their microscopic constituents.

dis is supposed 2 be about MATTER not heat

why not transfer the text to the heat pg??

[] ---What is matter? video -( Philip) it is 4 more den 1 class, Mr ellery
 * 1) Eh! I thought this wiki was only for one class!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi! Check out the powerpoint slide " The three states of matter" on this website: [] Hope you learn a lot! -Yi Hao Hi everyone! I researched that the five states of matter are solid, liquid, gas, plasma and bose! Is it correct? Please can someone tell me?? - Yi Hao thought so too.
 * I think //bose// means bio-einstein or something like that.

The three states of matter

Matter is anything that has **weight** or occupies **space**. Matter can exist in three states depending on how their particles are arranged. They are **solid, liquid** and **gas**(there is also plasma and bose-einstein)**.** Each of these three states of matter has its own properties.

The properties of matter

DENSITY -How much something **weighs** for its **size** is called its density. Two objects of the same size may not weigh the same.

VISCOSITY -A **viscous liquid,** such as paint, does not flow easily. A liquid with **low viscosty,** such as water, flows easily.

CONDUCTIVIY -Heat moves through solids very quickly. They are called good **conductors**. Plastics are poor conductors of heat. They are called insulators.

SURFACE TENSION -Surface tension holds water in drops. Water molecules are pulled towards each other.

Elasticity- A spring can be pushed together.It will regain its shape when let go.Elasticity is the ability to regain its original size and shape after it has been squeezed or stretched.

Hardness-Hardness refers to the ability of a solid to resist scratching. It is measured on Moh's scale from 1 to 10.tiny spaces between the threads of the cloth.These tiny spaces allow water to be sucked up by the cloth.Objects,such as plastics,do not suck up water.They have no spaces between them.

__**Matter**__ __**It expands when it comes into contact with heat.**__ __**It has 5 states: Plasma, Gas, Solid, Liquid, and Bose-Einstein.**__ __**Basically speaking, it has mass and occupies space.**__ __ What is "Bose-Einstein" ? __ __ Ellery __

__ Bose-Eienstein Condensate is a solid which is so cold that the the electrons, protons and neutrons combine together. __ __ Luke __ __ COOL!!!!!! __ __ ellery __ Um luke, you spelled Einstein as Eienstein. Mark___

Contrary to the previous view that equates mass and matter, a major difficulty in defining matter consists in deciding what forms of energy (all of which have mass) are **not** matter. In general, massless particles such as photons and gluons are not considered forms of matter, even though when these particles are trapped in systems at rest, they contribute energy and mass to them. For example, almost 99% of the mass of ordinary atomic matter consists of mass associated with the energy contributed by the gluons and the kinetic energy of the quarks which make up nucleons. In this view, most of the mass of ordinary "matter" consists of mass which is not contributed by matter particles. For much of the history of the [|natural sciences] people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called //particulate theory of matter//, was first put forward by the Greek philosophers [|Leucippus] (~490 BC) and [|Democritus] (~470–380 BC).[|[][|4][|]] Over time an increasingly fine structure for matter was discovered: [|objects] are made from [|molecules], molecules consist of atoms, which in turn consist of interacting [|subatomic particles] like [|protons] and [|electrons].[|[][|5][|]][|[][|6][|]] Matter is commonly said to exist in four //[|states]// (or //[|phases]//): [|solid], [|liquid], [|gas] and [|plasma]. However, advances in experimental techniques have realized other phases, previously only theoretical constructs, such as [|Bose–Einstein condensates] and [|fermionic condensates]. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the [|quark–gluon plasma].[|[][|7][|]] In [|physics] and [|chemistry], matter exhibits both [|wave]-like and [|particle]-like properties, the so-called [|wave–particle duality].[|[][|8][|]][|[][|9][|]][|[][|10][|]] In the realm of [|cosmology], extensions of the term //matter// are invoked to include [|dark matter] and [|dark energy], concepts introduced to explain some odd phenomena of the [|observable universe], such as the [|galactic rotation curve]. These exotic forms of "matter" do not refer to matter as "building blocks", but rather to currently poorly understood forms of [|mass] and [|energy]. Meng Loong
 * Matter** is anything that occupies space and has rest [|mass] (or [|invariant mass]). It is a general term for the substance of which all [|physical objects] consist.[|[][|1][|]][|[][|2][|]] Typically, matter includes [|atoms] and other [|particles] which have mass. Mass is said by some to be the amount of matter in an object and [|volume] is the amount of [|space] occupied by an object, but this definition confuses mass and matter, which are not the same.[|[][|3][|]] Different fields use the term in different and sometimes incompatible ways; there is no single agreed scientific meaning of the word "matter," even though the term "mass" is better-defined.
