What do all the physical properties of minerals result from? The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification. Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties. What are […]

How can I generate electricity cheaply?
How can I generate electricity cheaply? The IRENA report found that solar and onshore wind are the cheapest energy sources. It states that in 2017 wind turbine prices had an average cost of $0.06 per kWh, and at times dropped to $0.04 per kWh. What is the cheapest power generation? solar power schemes Is using […]
How do you calculate half-life examples?
How do you calculate half-life examples? The quantity of radioactive nuclei at any given time will decrease to half as much in one half-life. For example, if there were 100g of Cf-251 in a sample at some time, after 800 years, there would be 50g of Cf-251 remaining. After another 800 years (1600 years total), […]
What are natural esters?
What are natural esters? Natural esters are made from renewable natural sources, for example MIDEL eN 1204 (rapeseed/canola) and MIDEL eN 1215 (soybean). The base oil is chosen to give the best possible fit to the application; however unlike synthetic esters the properties of these base oils cannot be significantly altered. What are the main […]

Why are top predators so rare?
Why are top predators so rare? This energy constraint is the fundamental reason top predators are so rare. Many food webs consist of half a dozen or more trophic levels, and by the time you get to the top, there’s simply not that much energy left. It’s their naturally small populations that also leave these […]
