Is sugar a raw material?
Sugar cane accounts for 80% of world sugar production, making it the principal sugar-producing raw material. Sugar cane is a tall tropical grass. The stems are harvested, not the leaves. They are principally composed of water, sugar and fibres known as bagasse.
What are the raw materials for water?
Raw water is water found in the environment that has not been treated and does not have any of its minerals, ions, particles, bacteria, or parasites removed. Raw water includes rainwater, ground water, water from infiltration wells, and water from bodies like lakes and rivers.
What materials make up water?
To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature.
What is natural raw material?
Natural raw materials are any resources that are found in nature and that will be used to make manufactured goods. There are many different types of raw materials that are regularly used in this manner, including rocks and minerals, plants, oil, natural gas, and animal products.
What are the 4 types of materials?

What Colour is water?
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.
Can earth run out water?
While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. Also, every drop of water that we use continues through the water cycle.
Does water expire?
Though water itself doesn’t expire, bottled water often has an expiration date. This is because plastic can begin to leach into the water over time, contaminating it with chemicals, such as antimony and bisphenol A (BPA) ( 5 , 6 , 7 ).
Can humans create water?
The answer: very. Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy.

What makes water so good at dissolving?
Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.
