shale gas or tight gas, which is located in semi-porous or non-porous rocks that don’t allow the gas to freely flow when accessed through drilling. This natural gas can be extracted by using a combination of technologies known as horizontal drilling and hydraulic fracturing. PHYSICAL CHANGES – Physical changes involve a change in state. Do you remember what the three states of matter are? Solid, liquid, and gas. – In a physical change, the chemical substances DOES NOT become a new substance.

The changes that occur during a reaction just involve the rearrangement of atoms. In this section we will discuss stoichiometry (the "measurement of elements"). Chemical equations. Chemical reactions are represented on paper by chemical equations. For example, hydrogen gas (H 2) can react (burn) with oxygen gas (O 2) to form water (H 2 0).

Phases and Phase Transitions. Matter can exist in three different phases (physical states): solid, liquid, and gas. A phase is a form of matter that is uniform throughout in chemical composition and physical properties, and that can be distinguished from other phases with which it may be in contact by these definite properties and composition.

Another clue that a chemical change has occurred is the formation of a solid. A solid that separates out of solution during a chemical change is called a precipitate. As wood burns, it turns into a pile of ashes and gases that rise into air. After the wood is burned, it cannot be restored to its original form as a log. Chemical reactions involving the use of energy at the time of dissociation to form a new chemical bond is known as the endothermic reaction. Chemical reactions where the energy is released or evolved in the form of heat is known as the exothermic reaction. Energy: The endothermic process requires energy in the form of heat.

Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter. Chemical properties, such flammability and acidity, and chemical changes, such as rusting, involve production of matter that differs from that present beforehand.

The physical aspect: the candle heats the air and expands it. This cancels the depletion of the oxygen temporarily and the water level stays down. When the oxygen is depleted, the candle goes out and the air cools. The volume of the air decreases and the water rises. The temporary temperature change delays the rise of the water.
