What type of energy is used in an electric car? AEVs (all-electric vehicles) are powered by one or more electric motors. They receive electricity by plugging into the grid and store it in batteries. They consume no petroleum-based fuel and produce no tailpipe emissions. Do electric cars contribute to global warming? Plug-in electric vehicles (also […]
Is aluminum oxide toxic to humans?
Is aluminum oxide toxic to humans? Aluminium oxides rank amongst the less toxic substances and only exhibit toxic effects in high concentrations. However, the oral intake of aluminium oxide over a long time period should be avoided as elevated aluminium levels in the blood could cause side effects on human health. What is Al2O3 called? […]

What is addition polymerization in chemistry?
What is addition polymerization in chemistry? An addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products. Addition polymerization differs from condensation polymerization, which does co-generate a product, usually water. Addition polymers are formed by the addition of some simple monomer units repeatedly. What is meant by […]
Why does each element have a unique spectrum?
Why does each element have a unique spectrum? There are many possible electron transitions for each atom, and each transition has a specific energy difference. This collection of different transitions, leading to different radiated wavelengths, make up an emission spectrum. Each element’s emission spectrum is unique. What is the difference between action spectrum and absorption […]

How much density does wood have?
How much density does wood have? Wood density ranges from <0.2 g cm−3 in species such as Ochroma pyramidale (balsa) to >1.0 g cm−3 in species such as Diospyros ebenum (ebony), and is an important determinant of xylem water transport and storage properties and whole-plant water relations. Why is wood not dense? Wood is less […]
