The visible light emitted by the Sun is an example of matter. True | False 4. A microscope is an important optical instrument used for observing small objects. True | False 5. A molecule is a particle made up of two or more atoms that are chemically combined. True | False 6. ...
The properties of cow manure are vital, as the fuel can reach a temperature of 700 degrees in half an hour, and will be up to 950 degrees after another 20 to 30 minutes. The manure makes a good fuel because it is very high in organic material that burns readily and quickly. The manu...
He said one thing he found striking was the “exceptional quality” of some of the stones—very clear and with few fissures. The study is a good reminder, he reiterated, that there are always new sources, or new pockets from existing sources, being discovered, as is the case w...
Besides their long-lasting performance at low use levels (1 to 100 mg/kg), silicone antifoams are safe as they are chemically inert, they have a better resistance to heat and chemicals than ‘organic’ antifoams, they can be used across a wide range of pH range and are compliant with ...
Martinez: It’s not so much “Hey, we’re going out to nature because we have to take care of the trees.” We’re going out to nature because it helps you be healthy. It helps you live a better life. It’s gonna improve your, you know, math and science skills. Interviewer: Thes...
Only spandex made by DuPont can be called Lycra, but this fabric is chemically identical to fabrics that are called spandex or elastane, and it has the same attributes. How Does Spandex Fabric Impact the Environment? Overall, spandex has a negative impact on the environment. This impact is...
Traditionally, this step has been accomplished by soaking raw flax stalks, but these days, manufacturers may use chemicals to achieve the same effect. Before flax fibers are spun into yarn, these chemicals are washed away, but residual toxic substances may remain on chemically-separated flax ...
Chemically speaking, AGM batteries release energy by breaking apart oxygen and hydrogen molecules. When storing energy, these batteries recombine the oxygen and hydrogen in their cells, which is why AGM batteries are also a member of the “recombinant” battery family. AGM vs. standard batteries Th...
“PU is made in a strictly controlled and regulated chemical process, during which only a few grams per ton of chemical is ever released into the environment. The final polyurethane polymer is chemically inert, and therefore harmless. PU is also biodegradable by way of fungus found in landfill...
