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 flow is characteristic of macroscopic objects and systems, but its origin and properties can be understood in terms of their microscopic constituents.
Heat flow from a high to a low temperature 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 prohibits heat flow from a low to a high temperature body, but with the aid of a heat pump external work can be used to transport energy from low to the high temperature.
The SI unit of heat is the joule. Heat can be measured by calorimetry, or determined indirectly by calculations based on other quantities, relying for instance on 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.
Data ( /ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) are values of qualitative or quantitative variables, belonging to a set of items. Data in computing (or data processing) are often represented by a combination of items organized in rows and multiple variables organized in columns. Data are typically the results of measurements and can be visualised using graphs or images. Data as an abstract concept can be viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e., unprocessed data, refers to a collection of numbers, characters and is a relative term; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data refers to raw data collected in an uncontrolled in situ environment. Experimental data refers to data generated within the context of a scientific investigation by observation and recording.
The word data is the plural of datum, neuter past participle of the Latin dare, "to give", hence "something given". In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science or data processing: data are numbers, words, images, etc., accepted as they stand.

[Chorus: x2]
I be that chick on the other side, down til I die
When you need me I'll be there boo, I ain't gon' lie
Tell wifey I said hi, lick this, give her a kiss
As I, sit back and laugh about the ep she just missed
[Verse One:]
The chosen one, young lady never shady
Can't fade me, I'm gettin money
No dummy I'm actin funny, only true
thug niggaz with figures, six oh-oh's, I love them oh's
Peep' opposed, so I gotta get mine
The boy is mine, laid up in the whip
Gettin hit, that's the shit
Leanin to the back, gettin freaky like that
Who's fuckin with that, a 600 to a Hatch
Catch my flows, hittin you with low blows
Real chick on the side, take em for a long ride
Watchin my flicks, talkin slick
Kickin in doors, with the four-four
Smash you tricks, not your average chick
I cop guns and whips for you whores, mashin
It's all thugged out, your wife lose your her life
[Chorus]
[Verse Two:]
Girl I can't stand when he ain't around
He makes me nervous, takin trips out of town
to knock off this weight, but I truly understand
Money's sweet in Albany he gettin two hundred a gram
God forbid he get locked, or even worse bodied
What the fuck I'ma do, besides him I got nobody
Do he cheat? Probably, so what? I plays the mistress
in a see-through dress, then guess, what's in the chest
Nothin but gold and diamonds
Young thing, hard to find one
Bobby Brown on the lips, petiteness
Hotness, whoo, I'm talkin slick
[Chorus]
[Verse Three:]
Start a new beginnin never endin now I'm spendin
If enemy do', I got to let you know
I like the taste of moolah, do I have to school y'all?
His and hers mountain bikes, always livin right
My man keeps me tight, dressed in the best
Nothin more nothin less, caressin, blessin never stressin
Laid back fessin, it's early mornin, break of dawn and
now I'm yawnin, I take a sneak peek
Still how sweet my man creeps in stash box I hear a knock
Who is it? He said Feds, I'm here to visit
I opened the door, he pushed me on the floor
Searchin my house, why them tricks had to run they mouth?
Thangs ain't like it used to be can't you see
Bitch ass wannabes wannabe me
To-tti, whatchu gonna do when I come for you?
The same thing you been doin
