What does it mean when the two runners graphs cross? What does it mean when the two runners’ graphs cross? When the two runners graphs cross this means that in the graph above that runner 2 was behind but caught up and ran past runner 1 beating him to the finish line (40 meters). How […]

Is FCC stronger than BCC? FCC and BCC also have many different measurements within the unit cell, as shown in the table below. Additionally, FCC metals tend to be more dense, more stable at high temperatures, and more ductile than BCC metals. This comes from their packing arrangement and slip systems. Why is it called […]

What is the difference between the chemical name and chemical formula? Chemical symbols refer to chemical elements only. They do not necessarily refer to atoms of that element, but also to ions. Chemical formulas refer to compounds and, specifically, the ratios in which it is made up by different chemical elements. What is the chemical […]

Is water chemical energy? Water, like many substances, contains two kinds of energy. The first kind of energy is called kinetic energy. This is energy that is used during the execution of processes, such as movement. Because of kinetic energy water can flow and waves can exist. What form is energy stored in the human […]

What is the difference between rate constant and rate of reaction? A rate constant, k, is a proportionality constant for a given reaction….Differences between the rate of reaction and constant: Rate of Reaction Rate Constant It depends upon the concentration of the reactant It is independent of the concentration of the reactant. What is relation […]

How do you convert a smaller unit to a larger unit? To convert a smaller unit to a larger unit (eg to ), divide it by the number of smaller units which are needed to make. To convert from a larger unit to a smaller one, multiply. To convert from a smaller unit to a […]

What is the Joule equal to? One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one […]

Will a microwave explode? The water in their body heats up due to molecular resonance with the microwaves. Their eyeballs may explode from the pressure build-up as the water in them turns to steam with nowhere to escape. After a few minutes the heat will have penetrated deep into their bodies, causing their internal organs […]

Where does the sun go when it sets? Answer: The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that’s because Earth spins — toward the east. Where does the moon rise if the Earth rotates counter clockwise? The Earth rotates counter-clockwise on its axis […]
