What makes the Rhine River so important?
What makes the Rhine River so important? The Rhine is western Europe’s most important waterway. It rises in the Alps, and passes through Switzerland, France, Germany and the Netherlands before flowing into the North sea. The river is 1,320 kilometres long, and, because it is navigable from Basel to Rotterdam, it serves as a highway […]
Is Absolute Zero Possible?
Is Absolute Zero Possible? Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach. How do you explain thermodynamics to a child? Thermodynamics […]

It is the friction, experienced by a body, when in motion. (a) Sliding friction. (b) Rolling friction. (c) Pivot friction. 14.7. […]
What are the two types of reflection?
What are the two types of reflection? The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure […]
How many properties do ionic compounds have?
How many properties do ionic compounds have? Properties of Ionic Compounds Ionic Compounds have high boiling and melting points as they’re very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals. Is sugar a covalent or […]
