The mixture of carbon monoxide and nitrogen is known as producer gas and the mixture of carbon monoxide and hydrogen known as water gas. At 1273 K carbon combines with oxygen and nitrogen in order to form producer gas.

Carbon monoxide is a colourless, odourless and almost water-insoluble gas. It is a powerful reducing agent. It is also used in the extraction of many metals from their oxide ores like ferrous oxide and zinc oxide.

Carborundum is the second hardest material known and has a formula of silicon carbide that is SiC. It is used as a semiconductor at high-temperature and also in transistor diode rectifiers. Diamond is the first hardest material known.

Pressure (P) = Force (F)/Area (A)
From the above equation, we can see that the pressure is inversely proportional to area.
Hence, the pressure will increase when the area is decreased.

Pressure (P) = Force (F)/Area (A)
From the above equation, we can infer that the pressure is inversely proportional to the area and directly proportional to the applied force.
Hence, the pressure will decrease when force is decreased and/or area is increased.

Pascals Law states that a pressure change at any point in the fluid is transmitted throughout the fluid such that the same change occurs everywhere. This is employed in hydraulic machines by varying cross-sectional areas at required places.

Differentiation is the process undergone by plants in order to attain maturity. Development is the overall changes occurring in the life cycle of an organism. Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions. Redifferentiation is the further maturation of dedifferentiated cells thereby specializing for a particular function.

Development includes all the changes undergone by a living plant from seed emergence to death. Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions. Redifferentiation is the further maturation of dedifferentiated cells thereby specializing for a particular function. Differentiation is the division and growth of cells in order to mature.

Differentiation leads to elongation and thickening of sclerenchyma cells. : Development includes all the changes undergone by a living plant from seed emergence to death. Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions. Redifferentiation is the further maturation of dedifferentiated cells thereby specializing for a particular function.

Redifferentiation leads to the formation of secondary xylem and phloem. Redifferentiation is the maturation of dedifferentiated cells thereby specializing for a particular function. Development includes all the changes undergone by a living plant from seed emergence to death. Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions. Differentiation is the division and growth of cells in order to mature.
