What are the two types of batteries? There are two basic types of batteries: primary and secondary. Primary batteries are “single use” and cannot be recharged. Dry cells and (most) alkaline batteries are examples of primary batteries. The second type is rechargeable and is called a secondary battery. Can I use car battery for inverter? […]
What is the difference between genes and cells?
What is the difference between genes and cells? What are cells and genes? Cells are the basic building blocks of all living things, and genes can be found deep within cells. Genes are small sections of DNA that carry genetic information and instructions for making proteins, which help build and maintain the body1. Is a […]
What is done after the experiment?
What is done after the experiment? Once your experiment is complete, you collect your measurements and analyze them to see if they support your hypothesis or not. Even if they find that their hypothesis was supported, they may want to test it again in a new way. For detailed help with this step, use these […]
Is blood a heterogeneous mixture?
Is blood a heterogeneous mixture? Blood is a heterogeneous mixture because the blood cells are physically separate from the blood plasma. The cells have different properties than the plasma. The cells can be separated from the plasma by centrifuging, which is a physical change. Is Normal urine a solution or heterogeneous mixture? Normal Chemical Composition […]
Why backwashing is done in rapid sand filtration?
Why backwashing is done in rapid sand filtration? process. At certain interval of time, sand pores may get clogged due to fine colloidal particles and decreases the efficiency of filter bed. And hence it is needed to remove these fine particles from the pores of the sand. The well- known process for removal of these […]

Are railroad tracks hardened steel?
Are railroad tracks hardened steel? Railroad track steel is typically 1084 or equivalent hot rolled steel. This type of steel is great for heat treating. It’s tough, through-hardening, and forgable. Let’s go over the properties of this metal, some effective ways of working with it, as well as some good applications for the grade. Why […]
What is the relationship between volume pressure and temperature?
What is the relationship between volume pressure and temperature? The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro’s law). What happens to volume […]
Can you use distilled water as an eyewash?
Can you use distilled water as an eyewash? Distilled water should be used when making eyewashes. A very simple recipe for homemade eyewash is to boil one cup of water with one teaspoon of salt. This liquid can then be used alone as both an eyewash and a nasal rinse. Some recommend adding herbs or […]
How is pure tungsten made?
How is pure tungsten made? Tungsten is extracted from ore through a series of chemical reactions. Tungsten oxide can be roasted in a hydrogen atmosphere to create pure tungsten powder with water as a by-product. Tungsten powder is the starting point for tungsten mill products, including wire. Is Tungsten toxic to humans? Tungsten has been […]
