What is a join between atoms called? When two electrons are shared between two neighbouring atoms, they are said to be joined by a covalent bond. When covalent bonds form between atoms, the resulting entity is called a molecule with a fixed characteristic geometry. What is the basic unit of matter? In turn, the atom […]
Is 1 degree Celsius cold or hot?
Is 1 degree Celsius cold or hot? In the Celsius scale there are 100 degrees between the freezing point and the boiling point of water compared to 180 degrees in the Fahrenheit scale. This means that 1 °C = 1.8 °F (check the section about temperature differences below). What is the coldest Fahrenheit temperature? The […]
What kind of a wave is sound?
What kind of a wave is sound? These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave. How ECHO is created? An echo is made by sound […]
What is the difference between absorption and reflection?
What is the difference between absorption and reflection? Reflection means that they are thrown back from a surface; absorption means that they are incorporated by a surface and transformed into heat energy. Different surfaces reflect and absorb differently. The ratio between absorption and reflection is called albedo. What is P in Beer’s law? Absorption takes […]

What 3 components make up most magmas?
What 3 components make up most magmas? Magmas can vary widely in composition, but in general they are made up of only eight elements; in order of importance: oxygen, silicon, aluminum, iron, calcium, sodium, magnesium, and potassium (Figure 3.6). Which component of magma is the highest in value? Felsic magma has the highest silica content […]
Is it possible to cure myopia naturally?
Is it possible to cure myopia naturally? Myopia can be cured: MYTH Once this excessive eye growth has commenced, we can attempt to slow it down with myopia control treatments but we can’t stop the eyes from growing or reverse the excessive growth. This means there is no cure for myopia – only ways to […]
What are 3 uses of beryllium?
What are 3 uses of beryllium? Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites. Why is beryllium so expensive? Beryllium is […]
