Water (H2O) is the source of the molecular oxygen.
Carbohydrates, proteins, and fats are the main substances that provide the energy and raw materials that the human body needs. Carbohydrates are the body's primary source of energy, proteins are essential for building and repairing tissues, and fats are important for energy storage and hormone production. Additionally, vitamins and minerals play a crucial role in various metabolic processes in the body.
CO2 and water are raw materials. Light is the energy source
Light energy is indeed considered to be a raw material. This is because it does not need to be altered by humans to be used.
Those are raw materials. Sun light is the energy source.
The main source of raw materials for making polymers is petroleum or natural gas. These hydrocarbons are chemically processed to produce monomers, which are then polymerized to form different types of polymers. Additionally, some polymers can also be derived from renewable sources such as plant-based materials like cellulose or starch.
The raw water reservoir in a thermal power plant is used to store large quantities of water that will be used for cooling purposes in the power plant's condenser. This water is typically drawn from a natural water source like a river or lake and needs to be stored in order to ensure a constant and reliable supply for the plant's operations.
Yes, leaves use water and carbon dioxide during photosynthesis to produce glucose (sugar), their main source of food. This process occurs in chloroplasts, where sunlight is also utilized to convert these raw materials into energy for the plant.
A FRESH water supply, source of fuel (usually wood), and food/farms.
The main raw material for iron-making is iron ore.There are two iron ore minerals:haematite and magnetite.Actually haematite is an ore where iron is extracted.One can say that haematite is a source if iron.
EARTH
water is a renewable source of energy and is no more a raw material than wind or rays of sunlight. It can be however a raw material if used as one of the inputs in the manufaturing of a finished article (the output), and is charged as "raw materials" to an expense account in a company to the cost paid if (if there is any, i.e. tariffs and meter charges). It is a raw material only if used in the production process and is still present in H2o form in the finished good.
