There are two different ways that rocks are often classified; the first is based on the processes by which they form, in which rocks are classified as either sedimentary, igneous, and metamorphic. Rocks are also commonly classified by grain or crystal size.

A mineral is a naturally occurring, inorganic compound with a unique chemical structure and physical properties. A rock is a solid, stony mass composed of a combination of minerals or other organic compounds. For example, quartz and feldspars are minerals, but when formed together, they make a rock, granite.

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids. Rocks are always minerals, but not all minerals are rocks.

Heat is a form of energy, and energy is not a form of matter because it is not composed of atoms or molecules.

Salt water is full of sodium chloride molecules. are not poisonous and reactive like sodium metal and chlorine gas because they are electrically charged atoms called “ions.” The sodium atoms are missing their outer electron.

On earth, solid, liquid, and gas are the most common states of matter. Not only is water the most common substance on earth, but it is also the only substance that commonly appears as a solid, a liquid, and a gas within the normal range of earth’s temperatures. Water is a unique substance because its molecules a.

Water is unique because the properties of water allow it to exist in all three states of matter! Water is usually a liquid, but when it reaches to 32° Fahrenheit (F), it freezes into ice. When it begins to boil, some of the water turns into steam. (Steam is the gas state of water, and is also called water vapor.)

Water is the only substance where all three states can be readily observed in everyday life: solid water as ice, liquid water in a water fountain, and gaseous water as steam.

• Bose–Einstein condensate.
• Fermionic condensate.
• Degenerate matter.
• Quantum Hall.
• Rydberg matter.
• Rydberg polaron.
• Strange matter.
• Superfluid.

The seven states of matter that I am investigating are Solids, Liquids, Gases, Ionized Plasma, Quark-Gluon Plasma, Bose-Einstein Condensate and Fermionic Condensate.

Fire doesn’t fall into gas, because it doesn’t expand in the same way gas does. Fire doesn’t fall into liquid, because it doesn’t have a fixed volume. Fire doesn’t fall into solid, because it doesn’t have a fixed shape. Thus, fire is currently considered a plasma.

Fire is a plasma, not a gas or a solid. It’s a kind of transient state between being composed of the elements prior to ignition and the spent fumes (Smoke – solid particles and Gasses = Gas molecules.)

Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 2.0 million years ago (Mya). Evidence for the “microscopic traces of wood ash” as controlled use of fire by Homo erectus, beginning some 1,000,000 years ago, has wide scholarly support.

Classes of fire

• Class A – fires involving solid materials such as wood, paper or textiles.
• Class B – fires involving flammable liquids such as petrol, diesel or oils.
• Class C – fires involving gases.
• Class D – fires involving metals.
• Class E – fires involving live electrical apparatus. (

Class C Fires

A class C fire is one in which an energized electrical element is the cause of the fire. Class C fires may be started from faulty wiring, a short circuit, damage to power cords, overloaded electrical outlets, overheated or overcharged devices, etc.

ABC Fire Extinguishers use monoammonium phosphate, a dry chemical with the ability to quickly put out many different types of fires by smothering the flames. This pale, yellow powder can put out all three classes of fire: Class A is for trash, wood, and paper. Class B is for liquids and gases.

3. Do NOT pour water on the fire! Since oil and water do not mix, pouring water can cause the oil to splash and spread the fire even worse. In fact, the vaporizing water can also carry grease particles in it, which can also spread the fire.
