Teori1: Proses fotosintesis
Fakta1: Tumbuhanmemerlukan cahaya matahari dan gas karbon dioksida untuk membina makanan.
Di samping menghasilkan makanan, gas oksigenjuga dibebaskan.
Formula asas1: CO2+ photon(tenaga kimia dari matahari) → karbohidrat (makanan) + O2
Keperluan & IsuSemasa: Proses fotosintesis adalah penting bagi memastikan kepekatanoksigen dan karbon dioksida stabil. Hal ini kerana karbon dioksida adalah gasrumah hijau, iaitu gas yang memerangkap haba daripada terbebas keluar dariatmosfera. Dan ini menyebabkan suhu bumi meningkat. Oleh itu, penyahhutanan(deforestation) sedikit sebanyak telah mengurangkan proses fotosintesis,seterusnya menyebabkan gas karbon dioksida tidak berkurangan.

Teori2: Proses transpirasi
Fakta2: Bukaan liangstoma oleh tumbuhan semasa proses fotosintesis membenarkan air dibebaskankeluar ke atmosfera.
Kadar pembebasanair ke atmosfera dipengaruhi oleh kekuatan cahaya matahari yang memancar.
Formula asas2: -
Keperluan & IsuSemasa: Transpirasi menyejukkantumbuhan, contoh kaktus yang hidup di padang pasir dan juga membolehkan mineraldari akar disalurkan ke tunas melalui proses dinamakan reverseosmosis. |

Teori1 : Proses disponmantikle
fakta1 : udara diperlukan untuk mewujudkan angin tekanan untuk menggerakkan sesuatu.
Formula asas1 : CO²+ PieJ²= (23*45) / 3 anak kucing == Tinker
Keperluan & Isu Semasa : Disponmantkle apabila bergabung dgn proses kamasundel akan menghasilkan angin kuasa G20 berpesamaan dgn kuasa puting beliung yg terjadi di Florida sama la ngan hasil kentut 300 org akan mengeluarkan bau yg agak kurang enak malah menyedapkan rasa dlm nasi goreng. |

Teori: Water
Fakta: Water (H2O) is the most abundant molecule on Earth's surface, constituting about 70% of the planet's surface. In nature it exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a nearly colorless with a hint of blue, tasteless, and odorless liquid. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some of its properties may vary slightly from those of the pure substance. However, there are many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter—for other substances, see chemical properties. Water is essential for life on Earth.[3] Water usually makes up 55% to 78% of the human body.
Physics and chemistry
Water is the chemical substance with chemical formula H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.[5] Water is a tasteless, odorless liquid at ambient temperature and pressure, and appears colorless in small quantities, although it has its own intrinsic very light blue hue. Ice also appears colorless, and water vapor is essentially invisible as a gas.[1] Water is primarily a liquid under standard conditions, which is not predicted from its relationship to other analogous hydrides of the oxygen family in the periodic table, which are gases such as hydrogen sulfide. Also the elements surrounding oxygen in the periodic table, nitrogen, fluorine, phosphorus, sulfur and chlorine, all combine with hydrogen to produce gases under standard conditions. The reason that water forms a liquid is that oxygen is more electronegative than all of these elements with the exception of fluorine. Oxygen attracts electrons much more strongly than hydrogen, resulting in a net positive charge on the hydrogen atoms, and a net negative charge on the oxygen atom. The presence of a charge on each of these atoms gives each water molecule a net dipole moment. Electrical attraction between water molecules due to this dipole pulls individual molecules closer together, making it more difficult to separate the molecules and therefore raising the boiling point. This attraction is known as hydrogen bonding. The molecules of water are constantly moving in relation to each other, and the hydrogen bonds are continually breaking and reforming at the timescales faster than 200 femtoseconds.[6] However, this bond is strong enough to create many of the peculiar properties of water described in this article, such as the ones that make it integral to life. Water can be described as a polar liquid that slightly dissociates disproportionately into the hydronium ion (H3O+(aq)) and an associated hydroxide ion (OH−(aq)).
2 H2O (l) is in equilibrium with H3O+ (aq) + OH− (aq)
The dissociation constant for this dissociation is commonly symbolized as Kw and has a value of about 10−14 at 25 °C; see "Water (data page)" and "Self-ionization of water" for more information.
Formula asas: H2O
Keperluan & Isu Semasa: Byk kalo nk ckp kan tentang air ni. so aku pilih salah satu yg asas jer la ek...
Like many substances, water can take numerous forms that are broadly categorized by phase of matter. The liquid phase is the most common among water's phases and is the form that's generally denoted by the word "water." The solid phase of water is known as ice and commonly takes the structure of hard, amalgamated crystals, such as ice cubes, or loosely accumulated granular crystals, like snow. For a list of the many different crystalline and amorphous forms of solid H2O, see the article ice. The gaseous phase of water is known as water vapor (or steam), and is characterized by water assuming the configuration of a transparent cloud. The fourth state of water, that of a supercritical fluid, is much less common than the other three and only rarely occurs in nature. When water achieves a specific critical temperature and a specific critical pressure (647 K and 22.064 MPa), liquid and gas phase merge to one homogenous fluid phase, with properties of both gas and liquid. Since water only becomes supercritical under extreme temperatures or pressures, it almost never occurs naturally. One example of naturally occurring supercritical water is in the hottest parts of deep water hydrothermal vents, in which water is heated to the critical temperature by scalding volcanic plumes and achieves the critical pressure because of the crushing weight of the ocean at the extreme depths at which the vents are located.
In natural water (see Standard Mean Ocean Water), almost all of the hydrogen atoms are of the isotope protium, 1H. Heavy water is water in which the hydrogen is replaced by its heavier isotope, deuterium,2H. It is chemically similar to normal water, but not identical. This is because the nucleus of deuterium is twice as heavy as protium, and thus causes noticeable differences in bonding energies and hydrogen bonding. Heavy water is used in the nuclear reactor industry to moderate (slow down) neutrons. By contrast, the term light water designates water containing the protium isotope, in contexts when such distinction is needed. An example is the term light water reactor to emphasize that the reactor type uses light water. |
