What is common between liquids and gases. Gases are similar to liquids in that they flow; hence, both are called fluids. The primary different between gases and liquids is the distance between molecules. In liquids, the molecules are close together, where they c ontinually experience forces from surrounding molecules.
Injera is usually made from the tiny, iron-rich teff. However, teff production is limited to certain middle elevations and regions with adequate rainfall, so it is relatively expensive for the average household.
Viscose or more commonly known as Rayon, was made to substitute for the more expensive silk fiber. Though rayon is considered to be synthetic it is made from tree cellulose. Viscose is manufactured by treating purified cellulose in caustic soda solution to form a salt of soda cellulose. 2  It is pressed to remove excess caustic soda. 3  the soda cellulose is then squeezed and shredded to increase the surface area so as to make it more pliable to processing.
