How are atoms linked? Molecule is the general term used to describe any atoms that are connected by chemical bonds. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. What are three parts of an atom? Our […]
What is the symbol for phase difference?
What is the symbol for phase difference? (symbol: ϕ) The difference in phase between two sinusoidally varying quantities of the same frequency. What is meant by phase diagram? Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on […]
How does the kinetic energy of a moving body depends on its 1 speed and 2 mass?
How does the kinetic energy of a moving body depends on its 1 speed and 2 mass? Hence, kinetic energy is directly proportional to mass of the body and directly proportional to the square of the speed of the body. How does the kinetic energy of moving body depends on its speed? (i) Kinetic energy […]
Why is the mass conserved in a chemical reaction?
Why is the mass conserved in a chemical reaction? Even in a chemical reaction when atoms interact and create new products, mass is conserved. This is because the new substances created are composed of atoms that were present in the reactants. The atoms from the reactants come apart, rearrange and re-bond in a different arrangement […]
Why is Aluminium good for aircraft?
Why is Aluminium good for aircraft? Aluminum is ideal for aircraft manufacture because it’s lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum’s high resistance to corrosion ensures the safety of the aircraft and its passengers. Why […]
What are reactive metals used for?
What are reactive metals used for? Reactive metals, such as magnesium, are widely used in rust prevention and are known as sacrificial anodes. Iron will rust unless protected in some way. Reactive metals, when attached to less reactive metals, have the ability to prevent the less reactive metal from rusting. What are the five key […]
What is the 6 biggest planet?
Is the Grand Canyon a result of the flood?
Is the Grand Canyon a result of the flood? On sale since last summer, “Grand Canyon: A Different View,” by veteran Colorado River guide Tom Vail, asserts the Grand Canyon was formed by the biblical flood that Noah’s ark survived, and can be no more than a few thousand years old. Does the Grand Canyon […]
Do waves require medium?
Do waves require medium? Sound and water waves are mechanical waves; meaning, they require a medium to travel through. The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling. Why does electromagnetic wave does not […]
Which component of magma is the highest and the lowest in value?
Which component of magma is the highest and the lowest in value? Felsic magma has the highest silica content of all magma types, between 65-70%. As a result, felsic magma also has the highest gas content and viscosity, and lowest mean temperatures, between 650o and 800o Celsius (1202o and 1472o Fahrenheit). Could a mountain turn […]
